> Sorry but a living being that either had or has a penis will never be female and therefore is automatically uninteresting to me as a straight man.

I don't know why you think your sexual preference is of anyone else's concern except for people who would, before considering it, look at you as a potential sexual partner.

> Gender identity is a buzz word without meaning.

It (like both sex and ascribed gender) is a name for a very real phenomenon, whether or not that phenomenon is important in your world in which, apparently, the only thing that matters about other people is whether they fall in or out of your preferred set of sexual targets.

Like, I get that your identity as "straight" and your particular definition of what that entails is important to you, but I don't see why you get so intensely upset about a fictional concept of a society where people (whose self-image must not be as caught up in genital anatomy as yours for the existence of this choice to matter) have a choice that they don't in our present reality which would, if exercised, put them outside of your sexual preference (I mean, I would assume that the vast majority of those whou would choose it would, either because of their starting sex, or other reasons, already be outside of that set, anyway.)
