McGregor keeping alive the stereotype of drunk Irish thuggery.

In all fairness, earlier today, Khabib and about 10 of his Jihadi gang surrounded Artem Lobov, McGregor's teammate and confronted/assaulted Lobov. (See: Video: Khabib Nurmagomedov and Artem Lobov in altercation in Brooklyn hotel)

So, McGregor gathered some of his teammates for some payback.

Wrong? Certainly. But hardly unprovoked.

[Theoria]

Artem called Khabib a pussy on russian radio. Khabib confronted him to see if he would say it to his face. Artem backed down.
