Oh. You're one of those. Why does she need to justify her beliefs? Those were years ago. There's a reason companies don't look at your history from more than a year ago.
I have no idea what you're trying to say about Kyle but if you really care, they set up an arc for him in late season 1 so we can expect more from him.
And no. I can't pinpoint a moment where she changed her beliefs in the show because not once have they leaked into the finished product. If you consider a character having some flaws (which you conveniently left out) a sign of politics, then I hope you aren't reading any long books.
Also, the burden of proof is not on me because I'm not the one stating she's a racist, sexist asshole. The burden is on you.
