Ok. In the history, the gay people CAN'T admit that they are gay, or they will be beating to death, or just simply kill, or full of hatred because they are gay. What gay people do, they went to someplace that nobody would ever go, and they do the sex things and making out, everything, they are actually hiding. They call that a "The Closet".
Now, today, gay people want to be openly gay, not hiding it, or fear to admit they are. They don't want to be stuck in the "The Closet" anymore and want to open the closet to everyone, and accepting, as peace.
Now you get it?
