From time to time I'll spend all day posting racist trolling on the Web.
Why would you post disgusting language online?
What did you think of my trolling?
It is bad to troll people online and hurt their feelings. You should try to make the world a kinder place or people won't want to be friends with you.
That is a broad generalization. You need to understand that innocent jokes can also be hurtful.
Yes, and you're going to hurt a lot of people by trolling online. Did you know that trolling is pretty much just the act of making others upset? Does that sound fun to you?
