The Southern Poverty Law Center’s guide, The Alt-Right on Campus: What Students Need to Know basically advises you to network with everyone on your campus who isn’t a closet Nazi, meet with the Young Republicans (or whatever) and remind them that they’re inviting Nazis to come speak, and then to throw a big, fun event far from whatever Nazi is addressing your school and starve them of publicity and attention.
The rest of the guide is basically a Monster Manual for shitty people, with profiles of the chief Nazis, and their useful idiot shock troops like the “Proud Boys.”
The theory here is that trolls are fringey and naturally struggle to find people who are broken enough to join with them – but when we turn them into cause celebres, the ensuing publicity goes so far and wide that those thinly distributed potential supporters hear about the Nazis’ messages.
