Whether or not Morrissey is gay or "humanasexual" is a subject no one needs to debate or worry about. If such a thing were to hurt his sales in the United States, let them be hurt. The man can do whatever he wants and it is no business of anyone. If you're at a stage in your life where finding out Morrissey is gay is going to cause you anguish or grief, get over yourself.
Why did his stateside publisher edit out details of a relationship? Don't they know we don't use condensed books anymore?
