Of course humans are naturally xenophobic. We’re also natural selfish. We’re naturally killers, rapists, thieves, etc. Yet, somehow, we worked together to overcome that. We overcame selfishness by creating a society. We overcame the rest by making laws against them. And now, we’re to the point that the majority of us think that all those things are so horrible that we couldn’t imagine doing them.
At some point, we either got help from a divine entity, or created one to provide consequences for those natural things we do that can’t really be punished by law.
If we look at the real world, all forms of bigotry are less popular in young people. We’ve grown up being told they were wrong. And while many of the adults don’t seem to actually listen or draw a line in the sand where they will not change anymore, the children keep on progressing.
We’re also getting smarter. Every few years, IQ has to be adjusted downward. And the most intelligent people wind up working together more.
We have multicultural societies in cities, and the cities are already mostly against all this xenophobia. It’s the ones who don’t know people of other races who are the most racist.
In short, we have no reason to believe that xenophobia is, unlike everything else, going to win this war. Setbacks do not somehow prove that the battle is over.
And, if, somehow, the battle is one we are destined to lose, why would we ever want to stop fighting for what is right over what is wrong? If there is inevitably a rubber band, then at least we can make things better until it snaps back. And then we can do it again. And again.
Surely it will break, but, if it doesn’t, at least the times in between are good.
