You pretend as if you speak for nature but nature allows for homosexuality as well. Why do you seem so concerned with who's more common? It's a silly point no one is arguing.
The human condition allows us to make choices. Consider bees with their structured society. You won't find a worker bee deciding he wants to do beat box bee poetry. Why? Because it's not in their nature. On the other hand human beings can change careers, can change religions and belief systems, laws, life partners. That is totally within our nature. You don't have to legislate things that are not in our nature because we can not do things that are not within our nature anymore than a bee is able to do things outside of what is natural to bees.
Acceptance within the law and society. You can't claim to tolerate gays if you want to use the force of law to treat them differently.
