Any person or people who encourages, carries out, or threatens political violence, are terrorists. As some people have come to learn, said actions have consequences.
EDIT: I've been told for years by my opposition how "cancel culture does not exist". In almost every comment field I read comments authored by un-flaired users who the majority of you will never see, "I thought you guys were in favor of free speech", as some type of 'gotcha'.
While I will not encourage any bad behavior, my opposition has also always paired the above "free speech" with "but it doesn't protect you from societal consequences". This has always been true. The First Amendment simply protects your right of association, religion and speech related to that of not being pursued for it by the government.
For the massive amount of people who are losing their jobs? I doubt there's a lot of sympathy from our side. Unlike what some of you would like to believe, one does not have to say you "like Charlie Kirk", in fact, you can disagree with him, and you can say he was a bad man.
But you should realize what you're doing when you're celebrating or encouraging political violence.
EDIT#2: While these people with their vile reactions to Charlie Kirk's tragic death might not be the majority of my opposition, my opposition still completely fumbled this one. You could've come out and condemned it, you could've shown outrage for it, or you could've simply remained quiet.
