ZD,
What is the point of your story?
And it would seem that you do not know the story first hand, since you do not even know if the person who was publicly flaunting that they practice a perverted lifestyle was a male or a female.
I notice that that there was no allegation that the pervert was denied service. So it does not appear that anything illegal was done.
The pervert proudly proclaimed that he/she was disgusting and the person who noted it responded in kind that they are in fact disgusting.
What were you trying to say?
