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
I don't think cucks are "happily married" though... they may get off on the abuse, but that's not what marriage is supposed to be about.
