If you disagree with the theology and practices and tenets of a particular religion, don't belong to it. But, don't go to that church and purposely act obnoxious.
You have the right to behave as you want in your house.
Others have the right to disapprove of your behavior in their houses.
You have no right to anyone's acceptance and approval.
By the way - - I disagree with Mormon positions on most social issues. But, organized protests at Mormon temples remind me of Nazis picketing synagogues in the 1930's.
