I think it fucks up the marriage (divorce) racket for women due to the fact it's simply cheaper and a lot less hassle.

That's why it gets screeched about.

The bottom line is that it's no one's business what 2 consenting adults do.

How is it different than pouring $100 worth of liquor down some woman's throat at the bar, banging once and never seeing again?

Flame away, dgaf.
