You can only believe its no ones business if you have swallowed hook line and sinker that homosexuals are not mentally ill and not predatory.
Sorry, but the evidence overwhelmingly does NOT support that belief.
Homosexuality, particularly male homosexuality is a self destructive and predatory mental disorder.
Sorry, but if you wish to be elected to office, and you have a self destructive and predatory mental disorder, its absolutely the elctorates business to know.
So YOUR sexual orientation is everyone's business? MUST you tell us if you have a foot fetish or like to wear your wife's panties from time to time? MUST you tell us what role-playing games you and your wife enjoy?
It's NOT your business what someone's sexual orientation is unless they are doing something illegal.
