I know this is off topic, but had to respond.
I do not believe in blaming a whole race of people for any one excrutiatingly big problem. Nor grouping a race of people and stating 'they all feel a particular way'. However, lets review history. Europeans spread imperialism and colonialism leading way to racism that was then carried over to this country. So when you say "White people hardly invented the notion of racism." It feels like a defensive knee jerk reaction to a very sensitive subject, one that you're right- effects us all. I agree that those in all races have the potential for fear, hatred and discrimination of other races. But where is that derived from? As long as I have brown skin in this country I am still an "other". Laws may have changed, but attitudes entrenched within institutions that have existed here since the beginning of this country have not. In the short version, what the Europeans did was they brought with them the notion of white as being better in many ways to many groups of people all over the world. They did this through religion among other ways which seeped into indigenous and transported peoples mythology and psyches. Colonialization spread a notion of hierarchy that sought to rule the world, and it has. Institutionalized racism is a result of this power. And while not all white people benefit monetarily from this power, a white or lighter skin color still carries a worth/value in this society and in other colonized areas around the world. It is not enough to say that (racism) "belongs to no one group". I do think that everyone has to own up to their own forms of hatred (warrented or not) and follow them back to their roots and deal with them. But what if those roots are imbedded within a society that sees you as inferior? Both the questions and the answers are never simple. We still have to deal with the old model of the oppressor and the oppressed simply because it still exists.

And back on topic- I think that male feminist attitudes have as much to teach our girls and young women as well as boys and young men. Many of us don't grow up with a male figure that has feminist values and that can effect us very deeply, concerning how we are made to feel about/around the male gender and our relationship with it as a whole.
