You probably, then, also can see those predisposed to adultery organizing an adulterers pride march, even if they don’t actually engage in that perversion but merely “identify” with it, much as you see those marching in the aforementioned perversion they identify with.
Additionally, the idea they march “merely” to “identify” with the debauchery even without actually committing it, is purely an MO apologetic to attempt to justify the celebration of that depravity. Virtually none of the overwhelming majority of the non-religious participants in the parade see it as merely an identification of those predisposed to that unnatural deed whilst permanently refraining from engaging in it.
