I don't value blanket, unthinking "tolerance". As Marilyn Manson once sung "Love everybody is destroying the value of 'All hate has got me is nowhere.'"
"Tolerance" is often a mask for the game of social approval.
If someone drinks their own piss, so what? It may not be my cup of tea, but it's their prerogative. I might be curious to learn something about the practice to increase my understanding about acquired tastes, biochemistry, and even the imbiber's state of mind and reasons for doing it, but I have absolutely no need to give approval of it or validate it in any way.
