I think it's a quote from Mao, that means "letting a thousand school of thought happen". He's implying that the left wants every thought about sex to be valid. He means it as criticism, implying that no correct school of thought is valid to the left and that 'everything goes' in regard to sex.
Also, I'm with Zizek on this one. Fuck "fixing" the societal divide like Jordan wants to... It's pathetic. Where's fighting for what one believes? Where is the personal choice to have a political difference (and make even gross errors) possible in Jordan's world? There is no personal choice possible in Jordan's mind.
I don't honesly think that Jordan wants to "fix" the divide. I think he wants all the people to be like him and have a "centrist" quasi-conservative, liberal ideology. And deep inside, he wants to be the ideological leader of that movement, just like Heidegger wanted to be for the Nazi party. (We all know he's not a nazi, but the intellectual power hunger shows in both.)
