Of course not. I don't think I know anybody who's exclusively attracted to people who affirmatively identify as cis. I think everyone just needs to accept that sometimes straight people or gay people will be attracted to someone who has the body configuration typically associated with the binary sex they're attracted to but who doesn't necessarily self-identify that way, because the alternative is the facially ridiculous notion that everybody in the world is "really" pansexual and just has some sort of body-part fetish for penis or vagina or breasts or whatever.
And, yes, normal non-extremely-online people, including trans and nonbinary people, tend to realize this and accept this because they live in the real world.
I find Rhea Butcher attractive and they are non-binary.
