It's a good question. Not specifically about the London School of Economics, because that was started by Marxist Fabian Society members 125 years ago, but about a lot of academia.

Of course anarchism is a resistance to rule by domination, not to systems and procedures. Some universities are no doubt power centers, though.

edit: anarchism means "no ruler." It's usually painted by people who think rulers are necessary as something like amorphism i.e. "no shape."
