Not sure if this is serious. But imo,me,x,y or whoever "supporting" or disliking homosexuality doesn't really matter. People can think it's an illness or mental disorder or whatever,and their beliefs belong to them,as long as they don't harras others for being homosexual.
I do not think of it as a mental illness but even if it was? So what? Mentally ill people still have right to live as much as others. Hanging them or punishing them or trying to educate them won't fix a thing. Each to their own.
