Well, if what they said was true, you bet. That's the thing.
Yes, and maybe as a sitting head of state, Trump should have put some thought into who he was tweeting and whether or not it was actually true, because it arguably isn’t. Of course, if he’d actually thought about it, he wouldn’t have tweeted it.
When someone quotes the information from some source and, rather than discuss what the source said, people want to discuss the quality of the source, they are practicing agumentum ad-hominem.
Or maybe, as you’ve already suggested, people have repeatedly evaluated that source of information and found it lacking, and Trump, shockingly, is ignorant of that repeated evaluation. We don’t have to reinvent the wheel each and every time a source is cited and a head of state has an responsibility to act on the information that’s already out there on a matter.
It isn’t an ad hom to point out that a source is consistently full of crap and maybe you shouldn’t be repeating them if the source has regularly demonstrated itself to be full of crap. I’m not going to go to young-earth-creationists for biology tips.
I guess you’ve also missed the dozens of news pieces doing exactly what Trump should have done and analysed whether the information he was passing on was actually true or not.
I think Trump was trolling, and it seemed to work.
The only thing sadder than a LOL I TROLL U defence is when someone else feels the need to make it on behalf of someone else.
Equally, you can’t have it both ways. If Trump is just trolling, then why do we need to take his sources - and by extension, him - seriously? “LOL HE TROLL U” just means the Britain First dimwits and half of the other garbage Trump emits can be dismissed even more readily.
