Embarrassing shit from both of them. Neither came off well or like the tougher of the two. One guy flips the other off and pushes him, the other gives a weak slap back in return. Two dogs barking that don't really want to fight each other. Either man could have taken an actual swing, they both passed on that opportunity.
Personally, I think if you're a well balanced adult then you'll let yourself get called any name under the sun and not respond physically. There's nothing to gain and it's something we all should have grown out of by the time we got out of high school. Laugh that shit off. If hands are put on you in any manner though, even if it's just a push or a slap, you need to respond with violence. I'm all about being the bigger person and putting ego aside but that is assault and it is over the line. You swing instantly, whether you'll lose or not.
