How do you stand up to your parents?

Tell them whats on your mind about them or why you are mad at them and "fight fire with fire" or in other Words if they deny, you deny too (Ex: if they send you to your room) If they hurt you or threaten you in any way then just keep denying and hurt or threaten back but if it really gos bad then just look at them with a look of hate in your eye then turn stiffly, and go to your room with a fun device in your hand and DO NOT under any circumstances will you let them touch you.
