I've been watching Bob's vlogs for a while now and I have to say he's *always* like that. It's just now you happen to find what you consider your position in direct opposition to what you perceive his position to be and it's stung.
But like I said, go back and look at what he says objectively and you'll see he's not attacking people who don't like the ending, or are complaining about it in a rational and reasonable way. He's complaining about the self entitled morons who're making us all look bad. And I think that's fair enough.
