Different situations, different times. Conor insulted Muslims. So in his mind and community he will always be right. He would get praise regardless. That's why he's so huge in the Muslim world now. He shut up a thrashtalker and brawled with his team afterwards. That's why Poirier was treated with such respect, it's to show the world if you are humble to Muslims they will be humble to you. Poirier was used in that regard. Most muslims I train with don't respect grappling and call it hugging. However they respect Khabib after the Conor fight ask yourself why.
Tony is a guy that says random stuff, he's insulted Khabib many times and so did Khabib. When they see him they will try to intimidate him, it's just how it goes man. I can get into all kind of random stuff analyzing body language. He reacted smug, not worried and not flinched, It's like he knew the question would come up and played it off.
Just like the Max stuff, they come in with a gang and surround him, they run next to him and invade his space. If their crew walks towards Max training solo you'd feel the energy switch. And if they go run next to you that's testing you, if that was a Diaz brother or Masvidal they'd be on edge and adress the situation and either throw down right there or get out of the situation while making sure they wouldn't get into that situation again. Ask yourself why? Because it's bully behaviour.
It's setting everything up for a confrontation while they got you surrounded. That's what Hyena's do to their prey before they pounce. The moment they smell fear they pounce, or laugh at you and disrespect you then and there. In the streets it's either throw down or back off and get your shit taken if you're unlucky. If people test you and you're weak other fuckers will also try to take a bite out of you the next time.
That's why Conor flew in with goons and went ultra aggresive, he also understood the message that his friend did or did not get at the moment(Artem was intimidated, a friend of his got stabbed up while they were in Russia in a confrontation with Dagestani's) . But he understood if he didn't do anything now, they'd get punked again and again.
