Your comment implies that you think being gay is a choice. As you say, "they have less chance going back straight if they get them young"? If being gay is a choice, then tell me when it was you decided to be straight. You must also acknowledge the fact that if it is a choice, you suppress any feelings you have toward the same sex because you "choose" to be straight.
Edit: This was a reply to beeman, but didn't get nested under his comment. Apologies.
