I dont see why theyre concerned when its clearly all part of the plan.
Step one: make the domestic terror label a buzzword by using it as much as possible
Step two: use the domestic terror label on someone killed for innocuous reasons that is resisting (in no matter how small a way) the overall shit theyre doing
Step three: when people inevitably protest the innocent person being killed, label anyone who protests as a domestic terrorist (or supporter) and then kill indiscriminately
They literally just want to push the envelope to the point of being able to kill leftists without it being unpalatable to their base. Theyre pretty much already there. The main thing is just making it into a mutually-exclusive wedge issue in the minds of the base. Youre either pro-ICE or a domestic terrorist, zero nuance allowed, and suddenly its palatable to them to kill whoever they want
See also: the wedge of “trans/gender nonconforming people = pedophiles” that is the same playbook
