Fascists can't tolerate anyone who has a different world view to them. They want their opponents no-platformed. In their crusade, they don't want anyone with whom they disagree to have a voice. If their political opponents get injured or worse, then so be it, because they are vermin. 

What I have described above are also the tactics of the so-called anti-fascists, but they can't see the irony. And so last night a group calling themselves "London Antifa" stormed into a meeting of the Libertarian Society at King's College London. It was a successful raid for them as they managed to shut down the meeting. Job done. Fascism 1, Free Speech 0.
