What struck me about LOJ's flounce is that he looked to be getting irritated every time Julia spoke, even when she was making good points about gun control and not blaming Muslims.
He seemed upset that he was not dominant and then leapt on her 'shouldn't speculate too much' comments as denying the shooting was homophobic.
I think his 'oh you are going to have an LGBT voice' was passive aggression that weren't making it about him. If not, why leave when they were reading a quote from Stonewall?
