Is it good to be gay?

It's not just good, it's fantastic!
being gay is not a choice. So it is not good or evil. It's just who you are. Being a homophobe is evil.
The answer to this question depends on who you ask. Many conservatives would say no, it's horrible to be gay. Liberals would generally say that you are you are, and yeah, it's good. A lot of people are just in the middle, with an attitude along the lines of "it doesn't really matter, it's not good or bad."

Personally, I'm a liberal and I think it's neither good nor bad. You being gay is just a little, little part of who you are. It doesn't mean you're going to Hell - doesn't God love everyone? It doesn't mean there's anything wrong with you, either. All research has shown that gay people are born gay, they're not diseased or anything. So basically, don't worry about it. You were born that you, as Gaga would say, and that is definitely a good thing. Don't change it.

Good luck with everything. :]
