It's possible that the parades are celebrating learning about themselves, accepting themselves, and overcoming past instances where people would be literally killed for being gay (still the case in certain places, but since they have resources that we want, we allow it). The real dichotomoy is:
>it's not a choice
vs
>if you can't get a gf, you might as well try being gay
I've yet to encounter anyone who can justify point 2 without contradicting point 1.
