Ok then.....please point to some source (i.e. a census or study) that shows that most feminists are radical.  Any man or woman who advocates that women be treated as equals to men is a feminist, by definition.  This is the half of the population that is female, and a portion of the male half of the population.  We can plainly see that we don't have billions of radical feminists running around.

Feminism and radical feminism are not the same thing.  Some good summaries:

Feminism: en.wikipedia.org/wiki/Feminism
Radical feminism: en.wikipedia.org/wiki/Radical_feminism

Radical feminism, a relatively small group, is where you find those that are most likely to believe in and promote misandry.
