The "....matters" battle was a petty and shallow spitting contest highlighting how far identity politics has dragged civil discourse down into the gutters.
"All Lives Matter" was a disingenuous response to the slogan "Black Lives Matter" that was rooted in a semantically overloaded (and somewhat dishonest) set of statements.
Or, another way to put it.
One said claims to be focused on a cause that's aimed at addressing an issue, but lumping in a bunch of unrelated ideologies like "dismantling capitalism" and "dismantling the nuclear family unit and the patriarchy" (and then accusing people of not caring about the former, when they reject the group for the latter)
...and the opposing side responded, not with a well-reasoned argument or highlighting the glaring flaws I mentioned above, but rather with an equally semantically overloaded slogan that's about silly and disingenuous as showing up at a breast cancer 5k run/walk, and telling the runners "now now! we should be trying to fight ALL cancer!"
My response to the BLM movement has been direct and to the point. (both in online debate and in the real world).
I agree with the semantically stated cause, but if their movement wants my support... ditch the commie and postmodernist feminism drivel, and focus on the semantically stated cause.
Supporting the ideals of police accountability and addressing systemic racial inequality shouldn't have to be saddled with opposing capitalism and embracing whims of a gender studies major at Berkeley.
As I've stated before, a group could call themselves "StopSealClubbing", and if one of their side-mission statements is "dismantling capitalism", I won't support them...and I'll be honest about the reason I don't support them. ...however, if I rebuttal their movement by forming a movement called "StopAllAnimalClubbing" (with just as many overloaded undertones), then it would make me no better than the group I was opposing.
