Conservatives and right-wingers are the only acceptable target.
Why do you think Kimmel tried to characterize the killer as MAGA? Because he can't joke about him being gay, having a troon boyfriend, being antifa, not even about being a furry. Mocking right-wingers, even if they were victims of murder is considered safe comedy
Back then, Republicans were more Conservative & Dems were fine pretending to be Conservative. I’m pretty much a 1990 Conservative and that somehow makes me SuperMcMustacheMan.
