Partly. But it isn't necessarily Xenophobia. Those who have different cultures happen to be typically immigrants, but not always.
e.g. In Northern Ireland (and parts of Scotland) there were clashes between Protestants and Catholics. I used to see them all the time on the news when I was a kid. There are two distinct groups (both Christian) that have not co-existed very well historically. I don't know if you would call them different cultures but they are distinct enough to cause a schism.
If you have immigration into one country. These people with different cultures, have different values. That creates a schism between them and the natives.
e.g. You can see this in Spain between British Expats and Spanish Nationals. The British Expats essentially live in particular areas and they are their own subculture in Spain (I know I was one). I lived the entire time in Spain learning nothing more than being able to order Beer, Lunch, Taxi and working out how to use the automated bill payment machine at the BBVA.
Sure. That's a very generous interpretation. But I am quite certain OP does not mean "priviliged white dudes" as the issue with "multiculturalism". May OP can expand on what they mean exactly.
No it isn't a "generous interpretation". You seem to be taking very uncharitable interpretation while insinuating they are some sort of unrepentant racist. I am not sure why you are doing that. I find it extremely tiresome.
I deliberately gave examples where both groups were White Europeans so to avoid any conflation with racism. Otherwise the conversation is guaranteed to go nowhere as it ends up in accusations of people being secretly racist.
The problem is simply a clash of values between two disparate groups of people as they come from different cultures. The ethnicity of the groups is often irrelevant.
