It's kind of funny to me that these grown men were about to have a fight in the middle of a congressional hearing over a mean tweet, but saying "ass" isn't appropriate.
I watched the video and they both kept saying they would but wouldn't actually do it. Then both accused the other of being a thug/bully for wanting to fight but also a coward for not fighting.
Theyre the kids that act tough and pick fights in front of teachers knowing nothing can happen.
Now it might just be my bias, but I feel O'Brien was taunting trolling, while the hard-right guy was posturing. Of the two, I expect the hard-right guy to be more of the unstable child in the situation, but also agree probably not willing to actually fight. With O'Brien or however it's spelled, I feel like getting that reaction was his win... but again probably a lot of personal bias.
I don't think it's bias. O'Brien was seated throughout the whole thing and was talking calmly. He wasn't actually looking for a fight and was just letting Mullin make a fool of himself.
