Gay, it is because of genes or environments?

In my opinion, being gay is inherited. Once there's a member in your lineage who is gay, the male belonging to such lineage are predisposed to being gay. The environment is an added predisposing factor. When you are more exposed to an environment of gays, then it enhances your predisposition, causing one to be gay.

I don't feel that anyone chooses to be gay; You just are or You are not. It's part of your very being and is not something that is influenced by the environment. I am gay, my brother is straight - we were both brought up the same way. We are just two very different people
