as major a part of his life as "identifying as heterosexual" is for most heterosexual people.
That's a much more major part of certain heterosexual people's life than of others, and I'm not sure where the median is (assuming you mean “most” literally).
Agreed. (I agree it varies, and I too am not sure where the median is.) But I take it that if ChristianKI is arguing #2 rather than #1 then he sees "homosexual identity" as a bigger thing than "heterosexual identity" in some sense, and my wording was intended to invite him to consider someone for whom that isn't so. I can't nail down the details because I don't know in exactly what sense Christian (conditional on his intending #2 not #1) does consider homosexual identity a bigger thing than heterosexual identity.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
