What do the terrorist group Hamas and the anti-violence group Black Lives Matter have in common? What does the democracy of Israel have in common with the anti-Semitic Ku Klux Klan? What does the Islamic Republic of Iran, which throws gays off rooftops, have in common with gay right activists? What do feminists have in common with radical Islamic sexists who support the honor killing and genital mutilation of women? Nothing of course. Unless you subscribe to the pseudo-academic concept of intersectionality.
