I think there is something to consider a lot of straight people don’t want to be with trans people only because they aren’t attracted to certain genitals, which diff people have diff opinions on, but I’d say that still classifies as straight as just liking men regardless of trans or cis, and the person just doesn’t place as much emphasis as others on genitals. At least in college a lot of culture is around sex so people are usually concerned about that (which imo is dumb but still exists)
I hear what you are saying, but that is irrelevant. Say a man likes only girls, but not girls with brown eyes. He's still straight even though he doesn't like one subset of girls. Same thing with height, hair color, transness--ANYTHING. A woman being attracted to only men is straight, regardless of whether she likes only cis men, only trans men, or both. You can have a preference, but that preference is within the label of straight and that label doesn't change
