Maybe a testimony will suit you. I'm French. My parents are French. My four grandparents are Algerian. In case you also need that information, I am muslim.
I grew up in Lyon's suburb in what we call a ZUP (Prioritary Urban Zone). Yet, I am now in my last year of studies in mechanical engineering.
For 4 years now, I have been studying with a lot of people who don't really know a lot of young muslims from the suburb (that goes to show how the ghettoisation that started 50 years ago has separated citizens). I've never had any problems making friends for the sole fact that I'm okay with the fact that people joke on my origins. Hell, I often emphasize these jokes. (To be honest, a whole lot of jokes toward me are about me being dumb)
But I've got to admit that sometimes it is not that easy to hear the same jokes over and over. I still laugh, because they are funny, but when you meet new people, and they also do the same jokes, you start to feel that your face is laughable. (Here I thought I was handsome)
Further more, for a few months, I feel like a few people step back when they see me. I'm a 1m90, 80kg, 20-year-old man that can seem intimidating even with my lack of musculation. I don't even have a beard (it's not like I had the choice) and yet whenever I go for a run, I feel like people are fearing me. Yet,... I keep smiling.
I keep faith in humanity, and I always feel empathy towards anybody. People from all horizons don't have the chance to see the world as beautiful as it is. My life has made me meet people from all social ground, and I've had the chance to receive great education, from my parents, and my (suburban) teachers. Everyday, I still learn more and more from a lot of different individuals, and today I feel like sharing my view on this heartbreaking situation in which people can't discuss together.
I think a few thing can make it possible for us all to live together: - Breaking social walls (culture, sports...) : Knowing people from all social grounds is key to mind development. - Education from the parents : All people, whatever their (religion, origins, ...) should never teach their children neither hatred nor indifference. I've seen quite the number of children/teenagers from a social background who have misconceptions about the opposite kind of people. Once again, the development of a child's mind is key to his behavior. - Education at school : Once the two previous points are respected, I feel that it is easy to educate a child. - Giving a chance : I often hear my grandparents talking about discrimination. When my grandfather came to France to work, it must have been hell for him to face discrimination. I've never really felt discrimination toward me because my education gave me the tools to face such circumstances. People who don't have those tools may not be able to step up for themselves when they need it. (finding a job,...)
All in all, I feel like two sides are throwing stones at each other because none as tried to understand the other. It is the job of the politician to change it. But I strongly feel that segregating people, even if some are willing to be part of a ghetto (rich ghettos and minorities ghettos) will never solve this problem.
I could go on this for hours, but I feel like my argumentation is not strctured enough, and I am lacking the time to improve it.
Love your fellow humans!
