I'm going to block this guy
Is there a reason you're going to block him?
Yes, he is a cancerous person
I'm sorry that you feel that way about him. You shouldn't block people. Maybe you can talk to him and understand the reasons for why they do those things.
I don't give a fuck, block him. People can be rude and can't accept other opinions.
If you think he won't change, then I can't see why you wouldn't want to block him.
