The existence of trans people is not political! You're not fooling anyone. The "I just don't want politics in my media" shtick is a common excuse used by people who just don't want to see certain groups, because they're bigots. Would it be "too political" if a gay person showed up?
Don't make me laugh, most people don't give two shits about trans people, so Kamala advocating for their right to exist is not what lost her the election. It was simply because she represented the incumbent, and people wanted something new, or they just didn't vote at all.
