why cancel people is so normalized

The ''cancel culture'' is so normalized, like why are you canceling someone for doing something you did too? That makes no sense. Yall are so sensitive, you need a trigger warning for EVERYTHING, no one is perfect, and the ''perfect celebrity'' doesn't exist. And then you go bully someone for something they did or said even if they apologize, and after bully someone and try to cancel them for something you think is ''wrong'' you go and post a video saying that ''everyone has their own opinions and they can say it and express their own selfs'' but it is something that you disagree you try to cancel them, like wtf. If something doesn't affect you directly shut your mouth.
