radical feminism is a good critique of a society that is still inherently violent and sexualised. Radical feminists critique masculinity, not men. Men and women are indoctrinated with masculine norms - that women should be sexualised, sexually available, submissive etc etc. People get threatened by such critiques because it goes right to the heart of what is deemed as normal, and assume its all about men.
Take time to read Sheila jeffreys,Gail Dines, etc from their viewpoint and not the hate on them that abounds and make up your mind. You'll find what they say is far more rational than the hyperbole haters say about them.
Positives of radical feminism:
- they are the only group that critique gender, and advocate gender as a problem.
-they are the only group that provides a rational, comprehensive explanation to porn and its link to violence and female submission
-they are the only group that give due critique to masculinity in ALL its forms - psychological, verbal, physical and sexual.
-they are the only group that fully promotes that women can and should define their sexuality away from phallocentric notions and love as not inherently based on sex.
-they are the only group that opposes porn,prostitution and male sexual violence as one and the same ideology.
When you search on the internet for radical feminism, you only get rubbish from transexuals, transgenders, and liberal feminists who don't like that some radical feminists see the category of women as women born women and not trans*. Go read some radfem positive blogs, books, journals and come up with a more balanced view.
