Um, excuse me, not to be rude but I have something to say. Yes, what haters are doing is wrong, but hating them back is most certainly not the answer. I feel like if you were to negotiate, things would work for the better.
Not to be a Buzzkill, but in a way you're just as bad as the hater for hating the hater. Hate is a strong subject, and is not to be taken lightly. Do not hate someone for hating someone else, reason with them to change their opinion. By hating them, you are influencing hate as a problem-solver.
