On the other hand, my wife, being a Hijabi, did experience it in subtle ways (if we can call it racism): sometimes not-so-friendly gazes from strangers, she can not go to the public swimpool because burkini is not allowed, and she struggled for a year to find work even though she had a good engineering degree (the reason was not always disclosed, but some recruiters did explicitly tell her that it was because of her Hijab). Which is different from the UK and other European countries from what I have been told.
I don't watch French media, but I hear that that's where racism mostly emerges. And I must admit, the behaviour of some immigrant communities (especially some north-african ones, saying this as a north-african myself), partly justifies the hostile attitude towards them.
