Not biologically. This isn't a moral judgement, it's a biological fact.
There is a difference between tolerating homosexuality and saying it is equal to heterosexuality. It simply isn't for sexual organisms.
The statement was, "there is more to sex than just procreation". I didn't see where anyone said that primary purpose of sex was anything other than procreation. However, that does not mean that the only acceptable use is sex is procreation. If everyone had sex strictly for procreation, we would probable have trillions of people trying survive.Side effects, not purposes.
