Why are most religions agains homosexuality?

[Jehanne]

Most religions center around "traditional family structure which under girds the type of society Religion seeks to build. Homosexuality is anti traditional family. No mom and dad no kids. Homosexuality is typically centered around self or the individual want/need rather than a collective. which was the only way any young society had a chance in 'making it.'

Then there is the inconsistency of the atheists who think evolved instincts serve as a basis for morality. Having desires misdirected toward non-reproductive proclivities and undermining familial structures is similar to lacking the innate empathy that atheists say informs moral choices.

What does it matter to you what two consenting adults do in their private lives?
