You condemn physical violence but Robinson (not his real name) has a history of it. Aside from Robinson who was one of the leaders of the EDL, the EDL was founded by far right soccer hooligans out of Luton which are known for getting into street fights and attacking people.
They violently attack minorities, if that's not a big neon sign about the type of guy you are pitying currently.
For anyone else interested in the real truth read the section, A Long History of Fascist Organizing:

As for the video you are referring to, I wonder why people see physical violence as wrong but not manipulative violence like what Tommy Robinson does currrently. If you examine Robinson's intentions, there's a whole bunch of things that do lead up to the fact he's fascist including harassing journalists who were his critics.
Physical violence is wrong because it's reactionary but the Muslim Defense League quite literally ONLY exists as a counter reactionary movement towards the English Defense League's violence towards minorities in the first place. And let's not ignore the fact that the EDL uses that group to paint ALL Muslims as bad to further their agenda EVERY time the two groups clash.
