@FelipeInside: You're also naturally equipped to have heterosexual relationships. Why is one more wrong than the other?
The point about computers is that you think homosexuality is wrong because it is unnatural. Are computers somehow less unnatural than sexual attraction?
Comparing computers (which are tools made and used by humans) to someone's sexuality is totally out of context. Apples and Oranges so no idea why you insist on that.
Yes, we are equipped for heterosexual relationships, and breeding is only achieved that way.
