It appears to me that education must include diversity of experience. On the issue of Brexit I have heard about fears around new communities. I live in a diverse community where people come from all over this world. My housemates come from the African continent. They remind me that Africa is vastly larger than Europe.
I would have little in common with a Hungarian person. We are indeed all European and we should celebrate this. I recall that I have met a Hungarian couple in my church in Newcastle.
