Every culture at some stage has its dark ages, western countries did exactly the same thing not more than 200 years ago. They changed, all things change. Your argument regarding the high water mark of cultural morality could be used by Europeans about Americans currently (and frequently is). It doesn't make America a bad country in my eyes though, still find it amazing. I'm not going to judge each place by its lowest points but the gradient its on.

Given that I doubt you are following the high water of cultural morality as it shifts around the world, sounds to me like bigotry might be fueling you here.
