If homosexuals think that "everyone" should try homosexuality, what makes them so certain that maybe some "homosexuals" wouldn't be happier living as a heterosexual couple?
They discount the existence of bisexuals (they call them homosexuals who won't commit) and deny that some homosexuals are successfully "converted" to heterosexual activity.
Indeed. Bisexuals are a problem for homosexuals, but even more so are the growing number of ex-homosexuals.
