"right-wing political correctness monitors like Christina Hoff Sommers"
Based Mom is, in fact, a self-avowed
feminist.
The reason why she so often sides with libertarian and conservative groups is because she's disgusted by what she sees as the excesses and errors of the modern feminist movement and believes that these are signs that the movement has lost its way.
"Recent right-wing furies over
female Marvel characters"
This is a far more complicated matter than just "people don't want female comic book characters".
The long and short of it is that over the past few years, a number of comic book companies have set off on misguided "diversity" efforts wherein characters are being pushed
solely because of their gender or some other class membership rather than their being strong, well-written characters.
The majority of the characters being pushed as part of this effort are, quite frankly, one-note. The writers who are handling them are so busy pushing their class membership that they have consistently failed to develop them out
beyond their class membership, and in the case of the female characters it's become cliche for them to automatically be superior to any and every male character - including legacy characters - they happen to be with.
As if that wasn't bad enough, many of the writers behind these characters either explicitly created the characters because of their socio-political views (like Aubrey Sitterson and his complete re-do of the "Salvo" character from the G. I. Joe franchise [1]) or have begun to use these characters as author avatars so that they can spout their socio-political views to the masses (like the Sina Grace run on "Iceman" [2])
Between the $5 cover prices and the awful writing these characters represent, comic fans have been staying away in droves, satisfying themselves with $1 reprints and low-cost indie books. At a meeting of comic book retailers a Marvel rep was told
to his face that these "diversity" titles aren't selling and that the glut of unsold product is harming comic shops, but very few people within the established industry listened.
This is what long-time fans, including women, racial minorities, religious minorities, et cetra, are upset about: the fact that a series of poor decisions that include pushing full steam ahead on the failed diversity initiatives is doing severe damage to the industry.
The sad, simple truth of the matter is that IDW, Marvel, DC, Image, Archie, Valiant, and several others are in such a dire situation that either they will not survive the next decade or will be forced to mutate into a form we today wouldn't be able to recognize. That's how bad it is.
[1] The Salvo character, as introduced in 1990, was a buff, bald Caucasian anti-tank soldier with a fondness for edgy T-shirts. When Sitterson went to insert the character into his run on "G. I. Joe", however, the character had turned into an obese Samoan woman. In a 26-part Twitter spree he did in November 2017, Sitterson said that he made the change because he felt that the Hasbro-official design had an "alt-right vibe" that he felt needed to be "recontextualized" for the modern day.
Sitterson was already in trouble with Hasbro for insensitive remarks he'd made about 9/11 and for trolling a pair of fan websites, so when they saw what he wrote they forced IDW to fire him and cancel his Joe book outright. It's arguable whether or not Sitterson's firing precipitated the mass reboot of the Hasbro shared continuity IDW had going, especially given rumors at the time that Hasbro had been mulling whether or not to cancel the licenses IDW had.
[2] The first run Sina Grace had on Iceman was infamous for the fact that it focused solely on Iceman's LGBT status, which in turn was controversial as it contradicted decades of him being straight and actively dating women & had no lead-up. This culminated in an infamous issue in which Iceman's elderly parents, who were shown as being well-meaning but utterly confused, were treated as the villains of the book, with the issue's climax being his publicly humiliating them during a dinner in which they tried to reconcile and understand him. The book regarded Iceman as being justified in this, something that even some readers who were LGBT took offense at.
I am pretty sure it has something to do with the leading actor "Brie Larson" making exclusionary remarks regarding white males. The PR guys at Disney went full damage control, with her. Half in the bag guys response to this nonsense in their review is top tier.
To put it bluntly?
1. Brie Larson can't read a room to save her life. Couple this with what is a clearly over-sized ego, and we have the foundation for what appears to be a rather toxic personality. If you think her remarks about "old white guys" is bad, find the interviews she did ahead of "Endgame" and you'll see her go after her co-stars over innocent comments. Even in those interviews you could tell that Don Cheadle and Jeremy Renner were absolutely sick of her, and there are rumors that other cast members have had enough as well.
2. "Captain Marvel" was an inferior movie in multiple regards, from the shoddy effects work to the poor writing (such that Danvers is essentially a
villain for much of the film if you factor in the infamous deleted scenes) to the efforts to shoe-horn in "girl power!" as much as possible. If it hadn't had the Marvel machine backing it up, it would have failed.
3. Even apolitical outlets like The Film Theorists have noted evidence to suggest that Disney forced Fox to Nerf "Dark Phoenix" so that it wasn't any sort of rival to Captain Marvel, which Disney and the "good and proper crowd" had been going to length to push as the "girl power" event of the year.
4. Pursuant to the above, the same people were
also going to length to
destroy "Battle Angel Alita" because it had the gall to open before "Captain Marvel" did, thus stealing Larson's thunder. The fact that Alita was well-written, well-acted, and had bleeding-edge effects work while Captain Marvel was horrid and Dark Phoenix unwatchable has so frustrated the "woke" crowd that even to this day you'll find hit pieces being written against Alita and the film's fandom. That Alita was selling out within the first week of being available on home video while Captain Marvel is still cluttering shelves is taken by many Alita fans as final vindication.
"In August 2017, a Google engineer, James Damore, was fired after an anti-diversity memo he wrote went viral."
Translation: I didn't read the memo itself, and just assume he's anti-diversity, irregardless of him stating multiple times that he is not anti-diversity, and offer suggestions to improve the situation.
Pretty much.
Damore's memo basically said "Google's current diversity programs are so ham-handed in nature that they're causing more problems than they're solving, but I have some ideas on how to fix that."
But because he dared point out that a major corporation's diversity efforts were backfiring spectacularly he's been subject of a non-stop smear campaign.
