I believe that some blackguy in this case. He probably had no idea about that girl being a "race realist". If you're a poster who doesn't venture out of the coli safe space to debate/discuss things with people who hold widely alternative political beliefs to your own, it may be surprising to you that he didn't notice this prior to talking to her, but for ppl like me who are not sheltered to the coli and post all over the place, coming across individuals who believe IQ, to some degree, is determined by race is a pretty common occurrence. shyt, even ppl like Sam Harris is now arguing the validity of the Race&IQ hypothesis. Its not a rare position to hold on the internet, unfortunately, today, it seems like its the common position to find/hold on the internet.
So yeah, i'll cut some BlackGuy and ThatGuyT some slack with this one.
