It's not just swingers, it's is and has been about every group you can think of.
Christians being tossed to lions, the crusades, blacks, jews, mormons were declared fair game, literally in Missouri, muslims and arabs after 9-11.
I don't expect it to get better. There will always be people who think its the right thing to do to persecute others because they don't like their color, sexual orientation, religion, culture or the shape of their nose.
As Rick Nelson so aptly put it in his hit song...........
You can't please every one so you got to please yourself.........
Of course it's more fun pleasing a buncha people at once
