I once read somewhere that at least 2% of people you meet will dislike you, No matter who you are. This is the problem, everywhere you go you'll find people who dislike you but this is also true for every single person on the planet.

So it's not a matter of getting them to like you, you can't please everyone. Period. Stop the fighting, stop wasting your energy on them, just let them be, let them say what they want to say and have it wash over you.

The best way I deal with situations like this is to remove myself from their presence where possible, on Facebook, for example, I have people who are on my 'friends' list but I select 'do not show their posts' on my feed so I don't need to deal with them. This is just one example, have a think about how you can do this with the haters you're experiencing and reduce you're exposure to them.
