The right complains that "fascist" gets thrown around on by the left so much the terms loses meaning, but soon you'll be able to say the same about "domestic terrorist".
Its interesting to see at what point and how people try to wiggle out. Its a fun one because common counters of eg "Biden is a communist" are so easy to disassemble, ie im happy to define communist, agree it would be bad, agree we should fight against it, provide specific examples of things Biden could do to fit a communist description, etc.
It helps so far to help the right at least admit to their biased world view. not change it, but at least sort of see it.
