While that “ALL gays contribute to the breakdown of society..” may not be proven statistically, the negative effects of prevalent homosexuality is abundantly evidenced. More stats if you wish.
However, an atheist need not yield to such evidence, while their objectively baseless morality allows them to justify what seems reasonable to them, which in this case is homosexuality.
