There's lots of advice to give that has been given to this poster in many other threads. This one was about boxing.
The only thing he can do is to try to make it easy on himself. If I remember from past threads he's tried standing up and it didn't go over well. Sometimes all people can do is accept where they are and try to make the best of it while it lasts. Draw certain lines in the sand, like I'm not getting baptized, but go along the best you can with people that feed and clothe you while living a somewhat double life. Grin and bear it is the only advice in situations that are simply out of your control. Making a scene with people that can make things even more miserable is bad advice. Playing them so as to get the leverage or space to be able to be yourself where you can is way better in most situations.
The situation given by the guy earlier is the exception to the rule, not the rule.
