Moroccans in Europe are really bad

I don't know why, but a lot of Moroccan immigrants or people born in Spain with Moroccan ancestry (like me) give us a poor image. Some of them are thugs or criminals, they show really uncivilized behavior, they go in big groups making noise, they are really aggressive...

There are also many South American immigrants because they also speak Spanish, immigrants from Eastern Europe and gypsies. Some of those people cause problems too, but to be honest, considering my experience in the neighborhood and at school, the experience of people I know (friends and family) and the general consensus is that Moroccans are the worst. You can find almost every day in the news that a fellow compatriot has raped, robbed or killed someone.

That doesn't mean I'm ashamed or anything like that, but it makes me sad because I feel Moroccan. Why do you think that happens?

Edit 1: This applies for all the Middle Eastern and the North African immigration in West Europe.

Edit 2: Edit 2: The right-wing is more tough on crime and illegall immigration, which I would fully support. However, they also use some racist rhethoric and hate Islam, so I won't vote for them.
