No. On the flip side, being attracted to a trans woman does not make you gay/bi either (and yes I've had this very obviously transphobic argument presented to me)
A cis man who dates or has sex with trans women isn't gay/bi...but he's LGBT adjacent enough to be counted in the "+" that is LGBT+, perhaps? There was some article on this question several months ago that Alben Barkley got super offended by, IIRC
No, of course not.
Atlas in this thread is expectedly oblivious to the fact that one of the primary reasons most people want to form sexual relationships is to have children. A cis woman cannot naturally reproduce with a trans man, etc.
I do have two, very conservative cis male friends who are both in serious relationships with trans women. One identifies as bi and the other as straight, but the one who is straight has only ever dated trans women since college. Does this make him part of the LGBT community?
The counterpoint to your point though would be that not every cis woman can have kids either. Sterile women do exist, probably in bigger numbers than trans women.
While yout argument could certainly apply to a long term relationship, I don't think it applies to a one night stand of some sort.
What point are you even trying to make about sterile women? I think there are probably a lot of men who wouldn't want to date/marry a sterile cis woman, does that make them misogynists?
As for your point about one-night stands, I'm not sure what you're advancing but how could that not also apply to cis men/women? As in, if it's transphobic to refuse a one-night stand with a trans women is it homophobic for a cis man to refuse one with another cis man? After all, it's nothing serious amirite? lmao
