I think that it IS racist to not find someone attractive just because of their race, just like it IS transphobic to not find someone attractive because they're trans, by definition, as racism/transphobia is treating someone differently because of their race/gender identity. That said, you'd be perfectly within your rights to not find transgender people attractive. As long as you're not an *** about it (and so far you've not been), that's cool.
As for your list, in theory, androsexual people could be attracted to pre-op transwomen and post-op transmen, gynaesexual people could be attracted to pre-op transmen and post-op trans women, heterosexual men and homosexual women could be attracted to transwomen, heterosexual women and homosexual men could be attracted to transmen, ambisexuals could be attracted to transgender men or transgender women, heteroflexible/homoflexible people could be attracted to anyone, as could bisexual, demisexual or pansexual people. The list is longer than you think.
So, let me get this straight: George really likes Elizabeth, thinks she's very attractive and definitely hot. George learns that Elizabeth is actually black, and immediately decides that she's definitely not attractive and would never ever date her. And you don't see that as racist?
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
