Thallen to describe what you said more. Muslims are seen as a problem in the netherlands/belgium because they tend to be the cause of bad stuff according to the media. Mostly the muslim teens here are the ones who have caused all of this hate towards muslims in these countries because most of them simply don't behave well. They tend to hang around on the streets and people are actually sometimes scared to walk past them because they usually harrass you etc.
Even I prefer not to walk past a group of them because they have never not tried harrassing me or trashtalking me.

I've met a ton of nice muslim people ofcourse, but it's mostly the youth that ruined it for the others.
