If no one has "any right to tell others that being gay is right decision", then you don't have any right to say that it's a bad decision.
Just as you have a right to speak your mind, others have a right to speak theirs.
Do you see how that works?
Do you see that restricting others' rights means that your rights could be restricted?
Stand up for the rights of others. It's the only way that you can keep your rights.
