If it's because they are "trans" and nothing else, idk, sounds kind of scummy.

If it's because in general you simply don't find yourself attracted to transwomen, then that's perfectly fine, nobody should be forced into a specific sexuality/attraction schema. There could be various reasons, anything from perhaps the average features of a transwoman simply don't appeal to you to pretty much any other superficial thing.

If you really want to know what would be hypocritical, it would be if you were attracted to a woman so long as she was cis, but if the same woman was trans you suddenly wouldn't be (and because this is a cis comparison we'll assume this trans woman has had GRS), then yeah maybe it might be hypocritical, but at the same time never ever force yourself to feel like you should have to be attracted to any specific person either, though a little introspection as to why isn't the worst thing. Take the example with a grain of salt, it's probably not perfect.
