no, you cannot. because it's not a choice, it's not open to debate or opinion, and if you """disagree""" with a harmless, intrinsic, unchanging part of who somebody is, you are not only objectively wrong but also kind of a bigot.

it's like if I told you that I "disagree" with your race and it makes me uncomfortable for you to be so "overt" about it.

that would be a little thing called racism, just like what you're talking about is a little thing called homophobia.

please take your harmful, archaic """"opinions"""" elsewhere.
