People need to understand that immigrants (in general, wherever they come from and wherever they go to) don't really care about the country's history, immigrants coming to France today don't care about who fought for what 50 years ago lol, even if it indeed benefits them. Of all people, immigrants are the ones that are the most focused on the future, the very fact that they immigrated is that their focus is on building something better for themselves (or helping people out back home). So most immigrants will go along with the mainstream dynamics as the mainstream is where the financial benefits are. And contrary to local minorities, when push comes to shove they can always go back or move to yet another country. I've seen it here in France where brehs who grew up on the continent and immigrated here for studies/work just "go with the flow" and yeah might have a condescending view on local minorities who were born in the west yet struggle in life, while they just got here 5 years ago and own a house, two cars and might even have their own business already. And yeah a lot don't get involved in "the struggle" or whatever because their focus is mostly on the home country/bettering their own lives/the lives of their fellow countrymen (country of origin).
Ironically it's what the coli often champions : the "get yours" mentality.
There's a difference between first and second generation immigrants : first generation is "lay low, try to get into the mainstream, get money" while trying not to bring any kind of attention towads them, as the main referential is still the country of origin. But the second generation, born in the new country, often doesn't feel the same way and now has studied its history, grown up with the same mindframe as locals, etc. That's what's been going on in Europe.
