Why are you trying to? Tell them to fuck off, even if just in your mind. Be unapologetically YOU. You're a lovely woman, we've all seen that. I can list so many beautiful things about you easily, at the drop of a hat. If someone has an issue with who you are, it's their problem.
A prime example of this put in practice, to the extreme : T.r.u.m.p. He doesn't give a rat's ass no matter what a filthy human scumbag he really is. Because he's unapologetically himself, he has half of the nation caught up in his lies. That's the power of you being you and not giving a fuck about what others think.
