You do realize the DSMV diagnosis is dependent on body dysphoria, right? Treatment also revolves around such. You should consider that before straw manning lgbt status as being about social steryotypes.
Oh and I would very much love to have you provide some of those scientific and political reasons. Preferably with decent sources. Given your track record of citing and promoting groups from the SPLC hate list as trustworthy groups, I’m not expecting much on that.
