I was a bit young in the ‘60s for the huge antiwar demonstrations, but my sisters were not and their boyfriends were all making the scene down in DC. I played the role of the little brother and hung around at picnics etc... I did ask a few of the male friends why they protested. Without exception, save for cousin Danny (who is a 60’s version of today’s basement dwellers), they all said the same thing to the little brother (me). “To pick up chicks.”
It is the “cousin Danny’s” of the world I would keep an eye on. They’re crazy.
Leftist chicks were always easy and generally good lays.
