Sorry that it has taken me a long time to respond, I've been at the cabin, away from my phone.

Yeah the problem is that because of the history of discrimination we don't have words for relatively harmless discriminatory tendencies. So if I were to say

I have racist tendencies

it sounds like I'm admitting to being a "capital R" racist, when what I mean is,

I was taught incorrect stereotypes by media as a child, and sometimes despite my best efforts to be egalitarian, these biases cause me to make bad judgements. I try to notice when this happens, to make sure I treat people fairly.

Yeah I'm not saying anyone is a jerk for having sexual interest only with feminine people with vaginas and boobs, I'm just saying that it's kinda trans-erasure (and therefore technically transphobic) to say

I'm exclusively attracted to cis-women

Because a person doesn't know the assigned birth sex of every woman they've ever been attracted to.

OurToothbrush was offended because she is a transwoman and attracts men that think they're exclusively attracted to cis-women. She's on the front line of transphobia, and searching for a partner puts her at a too real risk of being murdered by a transphobe.

Yeah it sounds like absolution is a relevant term. People like to think that there are only biological males and biological females and that's that. It's not that simple. People like to think that there are racists and non-racists and that's that. It's not that simple. People like to think that there are transphobes and non-transphobes and that's that. It's not that simple. To me, being an ally is is about supporting a community to defeat unfair discrimination. Imo supporting individuals with friendship isn't exactly the same but it's better than nothing.
