Disgusting, lawless animals and their defenders on DU. A match made in Hell that we've seen innumerable times.
As someone with disabilities myself who was picked on repeatedly for them as a teen, I believe there's a special section of Hell reserved for people who mistreat the disabled, and the barbarians in this video most definitely qualify.
There is no doubt from any in their right mind that the video is real.
The "False flag/ undercover disruptors" explanation in particular is a total crock, because we see their faces (Disruptors generally hide their faces), see them committing the violent acts (Usually "Undercover disruptors" try to egg on protestors to be the ones to get violent, they don't do so themselves), and we see the facebook page for one of the attackers, which has been around for some time.
But, of course, since it's a hideous crime which even the DUmmies cannot provide a believable defense for (Their tried- and- true "They were righteously taking a stand against white racism" excuse doesn't work here, due to the fact that the victim was special- needs), they instead deny it ever happened in spite of all the evidence.
They're almost as loathsome as the attackers themselves.
