I try hard to seperate UFC and football/politics. Honestly, Conor McGregor for me is a person hard to try and not like, he's hell of a fighter and entertaining as fuck, but I also haven't looked in to his political views either.
Also the "fuck the queen" thing came from when he was criticised for wearing a poppy by the Irish and he told them, "You drink beer and wear a Celtic jersey in your local, fuck you and the queen." So maybe he doesn't really care what anyone thinks.
