"The so-called 'manosphere' is peopled with hundreds of websites, blogs and forums dedicated to savaging feminists in particular and women, very typically American women, in general. Although some of the sites make an attempt at civility and try to back their arguments with facts, they are almost all thick with misogynistic attacks that can be astounding for the guttural hatred they express."
Cited in the report were several MRA sites and other anti-woman/anti-feminist sites, some of whom I've written about before.
I found this report surprising and interesting. On the blogs I read, SPLC is famous/notorious mostly for listing anti-LGBT hate groups. This report is the first I've heard of the organization taking note of sites with alleged misogynistic content.
Also included in the report is a longer piece on the men's and father's rights movement:
"There are literally hundreds of websites, blogs and forums devoted to attacking virtually all women (or, at least, Westernized ones) — the so-called 'manosphere,' which now also includes a tribute page for Tom Ball ('He Died For Our Children'). While some of them voice legitimate and sometimes disturbing complaints about the treatment of men, what is most remarkable is the misogynistic tone that pervades so many. Women are routinely maligned as sluts, gold-diggers, temptresses and worse; overly sympathetic men are dubbed 'manginas'; and police and other officials are called their armed enablers."
Of course, feminist women, who are often on the receiving end of all of this vitriol, have been noting this misogyny for years (men call us things) (although, the SPLC report only cited the male-run "Manboobz" blog as calling these sites out).
Nonetheless, I'm sure this report will provoke a shitstorm of a reaction among MRAs and pick-up artists, with them creating their own "complementary" lists of feminist/misandric "hate sites."
