No wonder you're so warped with your idiot slippery slope syllogisms that ignore the laws of cause and effect. People contracted polio too back then. Maybe allowing more liberal bathing attire is the reason nobody catches it anymore as long as we're making random connections that have nothing to do with the facts.
And other countries more liberal with nudity don't have social problems any worse than we do, so that blows your theory to shit.
The answer is to stop listening to perverts like you who project the obscenity in your own minds onto the human body which is natural and comely to the mentally healthy viewer.
See, if you can't connect between increased sexual promiscuity and sex outside marriage and less emphasis on marriage and children(feminism tells women to "experiment", not have kids, get a job over a family) and higher out of wedlock birth rates, lower birth rates, and lower marriage, than you are not only a sex starved autistic nerd, you are a moron that can't connect the dot.s.
Your weak, libertine, feminist, "sex-positive" culture has led to a far worse situation in Europe. Europeans, if things stand, will be minorities in their own countries, as their birth rates and populations decline. Not existing and the decline of family and marriage are pretty big social problems.
You aren't mentally healthy, or normal. You are some sex crazed internet weirdo that has never had a normal functioning relationship with a woman. You resent people with standards cause you don't have your shit together and are a total loser.
