So wait a second, even if you have the nationality your considered a foreigner.
Not legally but yes there are social and racial discriminations (as there are here in the uk ) mainly for jobs up to 40% of young from foreign origin are without a job not always because they have no education.
Both sides, So you do understand why citizenship should be removed from someone but not another ,if both commit the same crime??
There is nothing to understand, this is an abomination.
No I understand why people who work hard don't like to find their car burned when they go to work in the morning and why youngster who are never given a chance in the society loose it riot and burn cars.

The problem with citizenship is: if one is given the chance to settle they should honour it, now without joking may be people should be given a five year residence before the real thing as a test. Another issue is what do you do with french criminal? where do you send them? to the US or Australia like the UK use to do with their criminals??

a nicer note: I knew a family in France where the father was a factory worker mother not working both illiterate from north africa: Five children, all have gone to university and done well one is a surgeon another a legal adviser one teach at Uni one in secondary school I can't remember the younger one but I think she was studying dentistry what I mean is: there are people who make it.
