You can say that petitions don't work. But guess what? the goal isn't to try to cancel it since that's probably not going to happen. The goal is to show HOW MANY people want it cancelled. When Japanese people made the petition to cancel assassin's creed, they knew it wouldn't be cancelled but they did it anyways just to let the world know how many of them were unhappy with it .
Actually this can apply to any woke shit we want cancelled
Virgin: help me daddy media/government/ratings authority, these poo poo movies are bad and hurt my fee fees. Ban them daddy!
Chad: it's shit, no buy
its shit. No buy
But also we want to cancel it.
What's wrong with expressing this opinion? do you want to be on the defensive all the time without ever being in the offensive?
leave a bad review and move on. don't engage with the culture war because it helps them with free publicity. the worst fate a piece of media can suffer is irrelevance.
ignore them. maybe even tell your friends to ignore them. but do not engage.
