The cultural friction is not a real issue except for the extreme right. The real issues are the same as everywhere: standard of living is going down for younger people while wealth is being concentrated in fewer individuals. Those wealthy individuals are the ones who benefit from promoting this immigration/cultural friction theory.
It is a real issue, because it's human nature. Groups don't like outsiders.
Pretending that isn't human nature is why anti-immigrant parties keep attracting surprising support in elections.
And that tension shouldn't be swept under the rug and ignored via the 'it's just the far right' excuse.
It's a thing. It needs to be addressed. Which doesn't necessarily mean implementing anti-immigrant policies, but does at least mean some form of address (e.g. government support for enculturation, advertising benefits of immigration, etc).
