The much maligned Vox Day had an interesting observation about how how to deal with SJW’s in his post How to lose to SJW’s. The advice is unlikely to be popular but I think he might have a point.
[What] would-be moderates fail to realize is that the anti-GamerGate, pro-Sarkeesian, SJW side is not reasonable and is never going to be convinced by sweet reason. They have no interest in it and little capacity for it.
This is the same divide between dialectic and rhetoric that I keep pointing out to everyone. You do NOT fight a rhetorical battle with dialectic; in a rhetorical battle the only use for dialectic is in a rhetorical manner; it can be used to explode pseudo-dialectic poses, but that is the extent of its effectiveness. It is an intrinsically defensive weapon on the rhetorical level. This means you cannot win with it.
The primary difference between the Left and the Right is that the Left instinctively defends its extremists and the Right instinctively runs from them and leaves them out to dry. The latter is an appeasement strategy, and it works about as well as the infamous failures of appeasement we all know from history.
All appeasement does is signal to the SJW what buttons he needs to push in order to force an opponent to retreat. When you dutifully point out that “you don’t agree with everything X says” or “don’t include the sexists, the woman haters and those who argue in bad faith”, what you are accomplishing is not the inoculation of your argument from their extremist taint, you are telling the SJW exactly how he can rhetorically defeat you by painting you as the very sort of extremist you disavow. And remember, rhetorical victory is the entirety of their objective!
Embrace the extremists. Defend them. Refuse to permit them to be cut off and isolated. Allow them to play their role as the intellectual shock troops they are. That is how you win. Because if they’re not taking the incoming fire, you are. And the shock troops are much better equipped psychologically to take it and survive than the average self-styled moderate.
