I like it too (east coast as well). I just see it as straightforward, though I've also been accused of having an offensive or off-putting tone when I thought I was being straightforward as well.
I don't see it as straightforward. I agree with a lot of what he says, but trash talk of pretty much any kind tends to distract of the issue at hand.
Like in sports or gaming, I always prefer the person who plays silently and speaks with purpose than someone who tends to trash talk while playing. But neither form of etiquette effects who is the better player.
