My definition of tolerance is allowing people to be themselves even when it goes against my own moral code and customs.. or makes me uncomfortable.
Nothing is preventing me from doing anything. I choose not to pick a fight with members of my family. Thats not being a coward by any stretch of the imagination. That is keeping the peace. Nothing I say or do is going to change the opinion of a couple bitter old bigots. It can sure as hell start a huge argument though.
Express yourself however you see fit. I'll tolerate it just fine. :)
