@darthgender execpt if someone is attracted to a woman and me or they are attracted to a man and me regardless of what their gender is they are attracted to two (and possibly more) genders and thus can be bisexual, same as if they were attracted to men and women. Saying that they cannot be bisexual implies that my gender is either less than a man or woman's (because it doesn't count in the same way) or that it can just be grouped into either man or woman (based on either presentation or ASAB) as if it was the same. As a nonbinary person, especially one who is not aligned to a binary gender, both of those implications are extremely offensive and hurtful to me. They both contribute to transphobia (implying my gender isn't what matters just my ASAB or presentation) and excorsexism (impliying nonbinary genders are not as valid as binary ones).
