When he took the office of Prime Minister of Luxembourg in 2013, Xavier Bettel became the third ever openly gay head of government. In total, there have now been five, all in Europe: Luxembourg is joined by Iceland, Belgium, Ireland, and Serbia.
Is that surprising? In this day and age? And if so, what's surprising, the fact there have been five, or the fact there have been ONLY five? (Remember, "openly gay". Ignore the Lincoln rumors, please. Now, James Buchanan, on the other hand...)
Now, there have been no gay Jewish heads of government, because we can't really count Bettel. He does have Jewish heritage, but only a quarter, and doesn't practice Judaism, so it would be tough for us to claim him.
A gay Jewish head of government... That'll be the day!
Don't act so surprised when it happens.
