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.
