I would worry too, OP.
When I was a teenager I wouldn't have thought twice about inter railing around Europe, especially Germany and Northern Europe. Now, not so much.
And it's only going to get worse. As a PP said, covering it up means some degree of tolerance.
Yes, Lauren, it's a hardly a new phenomena. But it's a new phenomenon in public places, where it's been covered up.
What are we supposed to do, sit down and shut up about it, quit our whinging? 
Because that's what women have been fighting for for centuries, freedom and women's rights.
We need to move fast or we are heading back to the Middle Ages, just like all those women in Iran, Iraq, ME, Afghanistan, Africa etc.
