The one that I go to which is more mainstream bordering (but not crossing over into) acceptability is Taki Mag. David Cole and some of the other authors on there do a really good job of discussing the negro problem in more acceptable terms. And they don’t give a shit how much pushback they get.
Another one is Counter Currents. Jim Goad writes there. More raw than Taki Mag, but I’ve read some really scholarly work on that site, too.
