It is actually more pleasant to be able to think of the actual causes and effects of events in the actual world than constantly ride a political hobby horse. Every wave of immigrants was bitterly resisted. The Natives of this continent vainly fought the white man. Ben Franklin was against German immigrants. Then there were the Irish, the Welsh, the Chinese, the Jews, the Poles, the Japanese and so on. It's always the resistance that loses. But lost causes give some people a sense of meaning in their lives.
