After reading this and this on the Southern Poverty Law Center website written about the Mens' Rights Movement, I contacted SPLC and asked if they'd run an article about extremist feminist sites. This is the reply I got back:

Just send any evidence to me (links, etc., are the best) and we'll consider it when the time comes again at the end of the year.

So if you know any extremist feminist sites, which advocate the eradication of men or somesuch agenda, please send links and relevant excerpts to [email protected]

Don't forget to be civil and also to thank him for the opportunity. And please publish your letters here as well.
