I doubt they’re offended. It’s more likely that, as a leftist, they are justifiably concerned about being provoked into making illegal (if morally justified) threats. There’s a long history of state agents infiltrating leftist spaces to provoke illegal behavior (which is often made illegal specifically to target leftists).

We don't need people that push a divisive narrative and push us away from each other.

This is the kind of shit astroturfing bots do, and it works, it's toxic AF.
