Versions of them are here already. Their focus right now is to:

• start violence at protests, especially around LA and target cities like NY, Seattle, Chicago, etc.
• seed doubt in anything related to the republican agendas or what they have done. Usually starts with, “I hate trump like the rest of us, but…” or something like that.
• downvote the shit out of people that call anything like the above out. They’ll come in later, one by one, to do this.

They usually congregate over the weekend and during or right after major events (like the protest). Watch for them this weekend or stay away from Lemmy. If you watch for it, downvote them and upvote the people fighting them, but most of all, take what everyone says with a grain of salt.
