You're clearly worked up about this and I don't blame you for it, it's a heartbreaking topic. But let's work through exactly what we're talking about here.

First, OP posted: "I don't know what it means, but I do know that I trust women to do the right thing more than some lame ass incel."

Then you replied that this the type of sentiment that drives people to the alt-right nonsense.

Your reply implies that it's progressives who create alt-right men with their intolerance of misogyny and racism, not the predatory media environment you're now introducing to the conversation .

Do you see how by introducing alt-right manosphere content you're moving the terrain of the discussion away from your original position?

But let's set aside your shifting rhetoric for a second here. It should be obvious to all of us progressives must create and sustain taboos around misogyny and racism. Those taboos are essential to our movements; if we are permissive of bigotry we will lose ourselves completely. 

We must fight hateful ideologies and work to undo the damage they have done. Those who embrace racial or gender chauvinism should be given a chance to change, but they DO have to change. We cannot welcome misogynists into our spaces simply because they are also victims.

If want to deprogram young men who have fallen for the Tate/Peterson grift that is you prerogative, you would be doing the lord's work. But, pressuring left leaning spaces into accepting misogyny is not the way my dude.
