There's tons of astroturfing from bots as well. Every other post about organizing is full of bots spouting negativity and right wing talking points.
In big threads on major subs they still get downvoted. In smaller ones you see then everywhere getting upvotes.
There was a post about the 34k people who showed at an AOC rally today and it was all "this won't do anything" "crowds don't matter" "this won't win elections" "liberals are losers" etc. Even saw some trying to call AOC and Sanders "oligarchs" lol
