What is morally wrong with homosexuality?

I have a request for somebody on this board to explain to me what is morally wrong with homosexuality.I understand that murder is wrong because you’re taking somebody else’s life, and society couldn’t survive under such conditions.I understand that stealing is wrong because you’re taking somebody else’s property, and society couldn’t flourish under such conditions.I understand that lying is wrong because you’re giving a person false information and distorting their view. Society would suffer under such conditions because people benefit from reality and truth, and suffer from a lack of it.So what is wrong with two consenting adults engaging in activity that harms no one?
