I couldn't disagree more. Our prudish ancestors had it all wrong. Ask the uncountable millions and millions of gay men and women who suffered their whole lives at the hands of those prudes. And what did the prudes gain in return? Bad sex and shame. There is nothing redeeming in an anti-sex perspective.

Whenever you find yourself saying someone is totally wrong, is a good indication you don't understand them.

I'm not going to argue with someone who can't see the other side. Presumably you can find some value in some of the values and traditions from the past? You have to acknowledge that our current values are merely an incremental change on what came before. You can't say they were all wrong without saying you're also wrong then.
