The problem with this is that it makes no difference what you say to haters, whether good or bad. Their bias and hate will always be the same. It's like a mental condition they have, it won't change according to what you say. Better to learn to recognise these kind and don't even bother saying anything. Anything you say won't be received well and although haters try to make it personal, it's not. They lie to themselves more than you. Live yourself enough to not fail foe their bait. I know some like this, they think you don't know and sometimes better to let them think that. When they find out you do know, their real feelings of hate fall through the cracks. It's kind of amusing, as when they hate they show a weakness which always falls back on them in the end.
