Nothing. This term is nowadays used by the lgbt... community to simply put a name to their effort to raise awareness about something every single person already knows about and for the most part does not care about (at least in my country).What exactly is there to be proud of?
What I find the most fascinating is that when I express my disappointment with having lgbt... stuff constantly shoved down my throat in movies, radio, television and work I get scuffed at because "I do not understand it."
While I am a zoo and I have 0, none representation anywhere and if I did dare to mention my "zoo pride", I would be considered the most disgusting person on the block and the first thing on their mind would be that I abuse my animals.
I do have a valid position to comment on the "pride" stuff from my position of having a minority and not publicly accepted sexual orientation and yet the inclusivity of people who praise the lgbt pride would not survive including another sexuality.
