If you examine "may have anxiety about their communities changing", it clearly implies they think non-whites are changing their community for the worse. It also implies the community belongs to the whites, and they get to define it.
Alternatively, they could (but don't) view their community as something they share, becoming more diverse, more interesting, more inclusive, etc.
It's not pretty in any circumstance.
It doesn't matter how the change manifests itself. People often dislike change, especially of communities they are familiar with.
Hence my point that it's not a problem with white people, but rather a condition of human beings. If a community of majority Latinos became subject to sudden white immigration, I'm sure there would be a certain amount of anxiety on the part of the original residents. I can understand and sympathize with these anxieties though.
Can you?
According to you, no one on Earth deserves to keep anything they have, because their ancestors took it from someone else.
Punishing a person for perceived faults of their ancestors is a recipe for ethnic conflict and racism.
No, I'm advocating non-empathy for people who lack empathy for others. Fear of the presence of other ethnicities and of their cultural influence is not an immutable characteristic of the European genotype.
Best of luck with your "non-empathy" approach, but I suspect it will make things worse for you.
And I'm not in Asia, so... fair enough?
People are not only members of "groups" that you chose for them based on their race, sex, country, etc. Each person deserves dignity as a human. Even if their ancestors and yours were enemies, it's not right to use tribal affiliation to judge them. Doing this promotes conflict and eventually violence.
A group is made up of many people and deciding how much "privilege" a group has is like asking the temperature of Europe. You can use math to average, but that doesn't mean much to a person in Turkey or a person in Norway.
If this same article were written about "rising anxiety among American blacks," many of the people insisting that we understand and respect the plight of the white rural male and recognize how justifiable their anger is, would denounce it as racist and ask what being black has to do with anything.
I can have sympathy for the poor, for the downtrodden and oppressed, but I can't have sympathy for someone who feels the mere presence of other races is a threat to their identity.
And they feel this way because they are human beings, not because they are morally callous.
Similarly, it's really just a natural human response that people of European descent are experiencing anxiety in their native countries when faced with large scale migration.
I think that a lot of people are unwilling to give sympathy to Europeans because of the recent history of European colonization across the world.
But it's not some failing of white people in particular that they in some cases may have anxiety about their communities changing. It's just a result of the human condition, human social behavior. As such they do deserve sympathy. Just like the hypothetical Iranians or Japanese in my prior example.
