I enjoy reading feminist blogs, even though my libertarian beliefs probably preclude most of the authors of those blogs from considering me a real feminist. Because I'm aware that my kind is not exactly welcome there, I rarely comment, but it's nice to know that I could. Unfortunately, there's a movement afoot on one of the more prominent feminist blogs to restrict comments in certain discussions to radical feminists only. Read the discussion that appends this post for a vaguely creepy description of how the poster sniffs out men and other undesireables.
