On the contrary - I view today's xenophobia as rooted in fear that a person may hold that their way of life will be wiped out as it has through human history. In other words - if it is built on a rational foundation instead of an emotional foundation, then education can help.
If things are as you described it, then isn’t that fear rational? What you seem to be saying is that people should hope that things happen differently this time than it did in history. That seems like the irrational part.
