I could certainly see this being something they're doing. Flooding the zone to give the impression of support. The problem with right wing rhetoric is that it's very attractive to the uninformed. It's really really easy to be a racist, for example. It's much harder to instill empathy.
I think it's working. Right as people were finally leaving Twitter during the election season and moving to Lemmy, Blue sky, mastodon, threads, etc. The election was already in full swing. So support on the left was fractured and disconnected from the main spaces where it would reach normal folks. Twitter, Truth Social, and Facebook remained strong and their message was everywhere all the time.
What do we do to stop it though? Grass roots grow Lemmy into something respectable? By the time it gets popular enough to matter, the right will invade and corrupt it.
And even worse? They're losing it all while the offending political party mocks and belittles them. Yeah, it's gonna get bad. They fly Trump flags in front of their houses and wear the merch and decorate their offices with it so...
It won't be hard for the resistance to find them.
