I love trolling racists.
Why do you love trolling racists?
They deserve it.
Racist people can be hurtful and mean but trolling them is also not good. You will just upset them and they will take it out on other people.
Whatever, they are basically already racists and bigots.
Trolling people you disagree with may be fun but it doesn't do any good. Try engaging them in honest dialogue, they might change their way of thinking.
