A few more thoughts because I'm trying to get tired and this popped into my head..
Not supporting a company, celebrity, or any other public figure because of their actions isn't "cancel culture". It's capitalism. People are allowed to vote with their dollar or subscription, and the reasoning is up to the individual consumer.
Some people say it's a violation of free speech. Uh.. no one who's been "cancelled" has been put in prison for their words. They just lost support from a significant amount of people once those people found out about behavior they don't see as acceptable. What you say and how you say it is part of your behavior.
And.... The people who use this as a "look, squirrel!" tactic are the exact same people fighting tooth and nail to do whatever they can to "cancel" anyone who doesn't agree with their conservative ideology. They are the same group of willfully ignorant, entitled fucks who say women shouldn't have autonomy over their own bodies and do everything they can to keep America dominated by white men.
They want to cancel abortion, freedom of religion (it's not not just for evangelicals or whatever judeo-christian nonsense they *think* this country was founded on.. it applies to Muslims and even atheists *gasp*.. All religions, or lack thereof is what America stands for) trans people's existence.. the list goes on. And on.
So, the term itself is used pretty much just used by white supremacists who don't know that they are in fact white supremacists or ignorant, media illiterate citizens who take politics the same way they take reality TV.
