Everyone celebrating Charlie Kirk's murder should be identified and fired from their job, expelled from school, and personally sued in civil court for intentional infliction of emotional distress. That's not "cancel culture," it's "consequence culture" to use the Left's own term.
These people are dangerous psychopaths who you can't trust to be your coworkers or classmates. They'd poison your coffee if they thought they could get away with it, and they'd neglect to warn you about a danger on a job site if they didn't like you or what your believe hoping you'd get hurt or worse.
Their hateful celebrations have no place in a civil society and they must be identified and held accountable for their celebration and encouragement of murdering conservatives.
