Male group bonding has nothing to do with homosexuality. Anthropologists say that the 3 strongest bonds are (in order of importance):
1. Mother-child.
2. Male-group (in hunting, trading, or warring).
3. Male-female.
This is why women "invading" male-groups can be divisive. It gets a class 3 bond going that disrupts the class 2 bond.
franco was much aligned, as far as i'm concerned he was a pragmatist and in many ways was somewhat humanitarian. spain was a haven for jewish children who were smuggled over the pyrenees by nuns during WW2. history is very complicated and not everything is picasso's guernica.
