I don't care about your religion, we're discussing the 'fact' you are presenting. Your religious belief doesn't give you authority about the subject.
You claim something that immediately turns out to be either a) greatly! exaggerated or b) just plain wrong in my world.
Germany has around 5% muslims, less than the 10% you talked about. I've been to a couple of universities (long story) and visited even more and I've had no trouble finding muslims. Not that I particularly cared, but w/o investing any time I can claim that your bold statement doesn't apply. Depending on upbringing and on how religious observant the families are you'll easily spot women, for example. And it's _far_ from rare to notice those obvious 'I'm a muslima' signs. Again: Yes, they are probably a minority - but how can they represent just 5% of the population and end up as 50% at the universities?
Bottom line: I didn't take the topic personal. 'Refrain from comment' is a bad advice. Using overly broad statements is just as bad. Insisting on being correct after people from around the world state other observations is plain wrong. I know that my comment was written in a harsh tone, but you could've reconsidered your point and come out good with 'Okay, my experience is based on ... and I might have tried hard to make a point, but the fact is that ..'.
Instead you call me childish and stick to your ~false~ claim. Why?
