if they want to have a march and argue for equal treatment then that is totally fine
You mean employment?
A guy walks in to apply and the mean HR lady says, are you gay? Yes, I am. Then, get out of here. Is this what you are saying?
Or is it: look everybody, I am gay, proud, on my tenth "partner" this week, have AIDS, and I would like to be a nurse in your hospital - preferably where blood transfusions are performed? Or, all of the above except that he wants to be an elementary school teacher who will tell the kids about the joys of making love to another man.
So, what equality do they want?
