Is RoK solely a PUA blog? Doesn't seem to be. The wikipedia
page on the "Men's Rights Movement" lists RoK as a "site dedicated to men's rights issues". And no I didn't just edit it. So we've got:
1. RoK founded by a guy (RooshV) who is closely tied to the PUA community.
2. Wikipedia calling RoK a "site dedicated to men's rights issues".
3. RoK making no mention of PUA in its rather lengthy "About"
section.
4. RoK explicitly disassociating itself from the MRM, but only by redefining the MRM in a way that's not entirely accurate.
To the extent it makes sense to draw a line between the MRM and RoK, though, I'll modify my claim: "There is significant overlap between those who share the stated goals of RoK, which have nothing to do with PUA, and the PUA community."
