This is the legacy of a country that never denazified, but still falls in line with Western hegemony regarding the imperialist project of Israel. They have found a new victim to foist their racist paranoia unto and simultaneously use the widespread opposition among Muslims and Arabs to Israel (a state that ethnically cleanses and exterminates them) as means to justify their extermination because their opposition to the Israel is systemically and legally classified as antisemitic.
This is the obvious consequence of labeling valid criticism of Israel as rote antisemitism is fueling anti-Muslim villainization and hysteria. If you oppose Arab extermination and ethnic cleansing, you are antisemitic. And if you're antisemitic you deserve extermination.
Immigration is going to be interesting for the west as a whole (due to generally shitty fertility and demographics). Right now there's a facade of the west being the most "tolerant/progressive" part of the world but that's obviously not the case. From imperialism to media coverage to structural socioeconomic issues, there's a lot of bullshit beneath the surface. In fact, this very sentiment is rooted in white chauvinism (or white man's burden) and therefore self-contradictory.
But as immigration numbers go up, more and more of the underlying racism and xenophobia will show itself and the facade will be stripped away. Structural and systemic racism will bubble to the surface, more and more yt people will become openly reactionary and vote for far-right politicians to keep the migrants out.
The positive flip side of this is that I see around me, is a lot of westerners being increasingly red-pilled to horrible the shit the west is doing. Immigrants are increasingly the friends, colleagues, neigbors, spouses and family of westeners. So racist propaganda isn't sticking like it used to. Don't know if I described it clearly like this.
I hope you're right. Seems like far right and neo nazi shit has made significant political gains in recent years.
