One of the biggest challenges the liberal order is facing in the West today arises from opposition to immigration. This opposition is understood, by the powerful for whom immigration provides access to cheap labor, as a sort-of racism that should be explained as an unwillingness to extend to foreign-born others the same rights we enjoy ourselves. Liberalism tends to universalize discussions of rights, so why shouldn't someone born abroad have the same rights as human beings born in America? It's obviously just selfishness on the part of Americans, a desire to continue to enjoy an unfair advantage (argue the masters of the capitalist order, who want these people to pick their vegetables at starvation wages).
That's not really what's driving the objection. The real force of the objection is that mass movement -- immigration or migration within a nation, doesn't matter -- disrupts and destroys communities that are the basis of almost all human meaning. It's not really an objection to the people coming in as if they were inferior people: it's an objection to communities and cultures being destroyed, when those things are where we get almost all of the sense of meaning we derive from human life.
A culture is defined as "a way of life." Ways of life exist among people who live together and share personal connections. You don't know and can't know everyone, but you do know the nice lady at your favorite coffee shop, or library, or bar; you know the people you met at church, or work, or school. You grew up participating in institutions like a church or the Boy Scouts or your town in your home state, with its local sports teams and friends you know from interactions around the place where you live. Together you have built a culture, and it really does depend on the stability of all those things.
While you get a certain amount of your sense of meaning in life from philosophy or your personal engagement with religion, most of your sense of meaning and being important comes from your interactions with other people. Those are the people who are part of your culture, including your family. When the institutions, including the family, are badly disrupted you lose the connections that make your life meaningful and worth living.
Of course human beings object to that. If you want a universalizing explanation a la liberalism, this is a universal human drive that is at work.
You can see just how universal it is by looking at the phenonmenon of objections to gentrification. Now gentrification has clear benefits, just like cheap labor results in cheap vegetables. The gentrifying town is getting nicer. Those who lived there thus have a nicer place to live, with less crime and better shops. They might even get a better job as wages increase and labor is needed by those better shops. Yet gentrification, another localized form of mass movement, is objected to just as strongly as mass migration of any sort. The people objecting to it are often on the other side of the spectrum of economic life, too: it's the poor objecting to rich people moving in, rather than richer people objecting to poorer people. The problem is the same one, though. The gentrification is disrupting the community, forcing people to move out as well as they can't afford the higher taxes and cost of living. Soon the institutions that sustain a meaningful life are broken up, families are dispersed seeking places they can live, churches cease to exist, and individuals are stripped of the relationships that made their lives important and worthwhile.
Liberalism doesn't have the machinery to address this basic drive. As mentioned it responds to objection to migration with charges of racism; it responds to objections to gentrification with a defense of property rights. The richer people bought that land fair and square, and now it's their land to use within the forms of the law.
Meanwhile even positive laws can't be allowed to violate fundamental rights, and both "equality of rights" and "property rights" are fundamental rights. The law might oppose illegal immigration, but you can't stand on the law when people are suffering: that violates their equality. The law might support gentrification, which is an exercise of a fundamental property right, so you can't oppose gentrification without breaking the law.
Part of the reason there's such fear of fascism in spite of an absence of fascism is that the opposition arising from this basic violation of a human need are characterized as fascists. Some of them, indeed, adopt the term for themselves because they also -- being liberals -- lack a conceptual non-liberal way of understanding this drive other than the one they are being charged with by their opponents. So they start chanting Sig Heil, accepting that they must be fascists because they can't walk away from the basic human need that the system is violating.
Mostly people don't do that, though. Mostly they just put up with being miscatergorized, and fight for what they know they need without having a way to explain that need that makes sense to others. Because the liberal order doesn't have a language for this, they can't make themselves understood to their opponents, and ultimately we aren't able to reason together about these problems.
That's too bad. Unless we find a way to transcend that contradiction, as Hegel might say, we're going to end up fighting over it. It's a stupid fight, too, because all human beings really do want the stability that allows for a flourishing community in which they can find meaning and durable relationships. The liberal/capitalist order violates that stability by its nature, because it is always organizing for maximal freedom and maximal economic efficiency. Stability gets in the way of those things, and thus is thrust aside. Literally everyone is less happy as a result, and yet the intellectual framework keeps us from being able to talk with each other about it.
