As always, he does everything he can to stay in the media. Connor really shows more and more what not to do to become a good fighter. Newcomers just need to look at what he did after his career ended and do everything in reverse, and success will be guaranteed.
I think that no sane person likes what he did after finishing his career. I'm not a huge fan of his trash talk, very often he was very disrespectful and offensive. He said it all was said to sell the fight but it doesn't worth to sell the fight by humiliating your competitor's family members.I don't know who was in the wrong here, maybe the guy have said something he shouldn't, but, nevertheless, McGregor is on a downward spiral and he's not aging gracefully. He needs to sort himself out and find a meaningful way for the rest of his life. Abusing substances and hookers won't take him anywhere.
There is a very high chance that Connor was wrong here. He is an overconfident guy who does whatever he wants and doesn't get punished for that because he has a fame and lots of money.I dont know the story around that situation on Ibiza, but whenever someone sees a professional fighter, I really dont think that this person will try to say something bad, disrespectful or try to piss off a fighter. That would be just stupidest thing to do, because a pro fighter, even former or a drunk junkie like Conor, can whoops regular persons ass easily 
No, some fans really do that. I've seen a few videos of fans provoking Merab Dvalishvili. In one video, fan disrespected him and then Merab quickly reached him and then this guy was like, sorry, sorry, I didn't want to. Some people are insecure enough that they try to disrespect strong people with the hope that the security will protect them. A few years ago, someone annoyed Mike Tyson on the plane and then he got punched in the face for that. Some people are just insane but in this case, I think that Conor would be provoker of the fight.
