Of course it is and it so, too, with all sexual confusion. Making mental disorders socially acceptable doesn’t make them not disorders nor does it make them natural nor does it make them safe nor does it make them good.
Actually, mental disorders are completely natural. Unless you subscribe to the pseudo-religious belief that "natural" is a synonym for "good and pure", you know that "natural" illnesses absolutely should be treated.
Cancer, schizophrenia, and Ebola are all natural, but I've never heard anyone claim that we should celebrate them instead of looking for cures.
