I am 87% Ashkenazi, more than most Israelis. OK, three of my grandparents were Jewish but how my Irish grandfather got to be half Jewish will forever remain a mystery.

I don't buy "race is a social construct" any more than gender. It doesn't take too many generations of geographic isolation between two colonies of a species before they can no longer interbreed.

There are differences. They're just not superiorities or inferiorities.
