I can't believe that you think feminism hasn't infected people in the US. You can't really think that.
Women training with men in the military. Title 9. Women firemen, etc. Girls being pushed into careers via propaganda from the time they're 4 years old. Boys emasculated and vilified ditto. E-Z divorce. Kids pushed into daycare. Lesbianism. "A woman needs a husband like a fish needs a bicycle". Abortion as a sacrament. Equal opportunity sluthood. etc etc etc.
When you say that feminism hasn't affected real men and women, you're right if you mean that it hasn't changed our minds or our actions. But it has crept into our legal system, our schools, our speech and writing; it has affected the fact that millions of children are now being raised without fathers in part because of feminism, and that men are devalued. That means that there is a higher crime rate, which certainly affects even those of us real men and women who have backbones and gonads.
