Actually it seems pretty simple to me as well...
I have no problem with someone living as they choose...even if their choice seems foolish to me.
What I do have a problem with is those who attempt to force others to agree with their foolish choice.
i.e. That freak who sued a business because they would not do a Brazilian-Wax on his privates, I can never be convinced that that fool in a dress and garish makeup should be able to force someone to do such a silly thing.
Like I stated, you’re argument is with God and His factual reality of MALES & FEMALES.
