Apparently I am the only one who considers it an act of humiliation.

... not completely the only one:
Google: peeing on someone meaning
I got the response:
verb, rude slang To treat or regard someone or something with utter disdain, contempt, or rejection. The boss is always pissing on my ideas.

To me the actual act is much more powerful than the words, one of the highest forms of humiliation.

You are not alone. I too consider it to be an act of humiliation (indeed one of the very few things can humiliate me dependably). I suspect this is because I am two parts masochist one part submissive. If I were completely submissive I might be one of those who regard it as an honor.
