Despite their occasional claims to the contrary, bigots seldom hate only one group. And when they are allowed to display these feelings, the whole spectrum becomes visible. In our own country, witness how unopposed anti-White rhetoric of the last four decades translated into open anti-Semtitism and attacks on Kirean grocers during the LA riots. Hitler's brigades, too, did not stop at the Jews: Gypsies were esterminated, and Slavs treated as slaves.
All too often we allow bigotry to continue unopposed, especially when it hides under the veil of civil rights or class struggle; or, as in the case of Pat Buchanan, isolationism.
