Yes. "Doing a lot of organizing" is very specific. Dude needs to be calling on states to use their national guard and police to remove ICE agents breaking the law (which is all of them).
But yeah, organizing campaigns for other do-nothing Democrats is just as good.
You really need to raise your standards for "specifics". Bernie and AoC should be leading resistance and they have done nothing but "point at" the bad things while taking no action and definitely not speaking in "specifics".
The majority of people that use Twitter are just everyday people that literally don't follow news or politics apart from the random stories that catch there eye on Twitter. If all of the left wing reporters and commentators left the platform it would literally just be Nazis and everyday people. (Which is what is happening). And the only stream of "news" coverage people would see is Nazi shit.
The issue is not with individual people deciding to support a Nazi owned platform. The issue is that the main form of online discourse is allowed to be owned and operated by a single billionaire Nazi.
Leftist that expect other leftist to leave a platform that reaches the most people are not being strategic or helpful. You have to meet the masses where they are at. You post leftist propaganda in the town square, even if the town square is owned by Nazis. You don't post the propaganda in your leftist only safe space and expect people to be exposed to it.
By all means, leave Twitter for personal reasons. Harassment, mental health, etc. But don't cry about leftist aggitators remaining on the platform.
Twitter is far larger than anything their "support" could be doing. It's the equivalent of being upset at the guy not using a paper straw and saying that they're the problem with the climate.
