I've seen my share of live stand-up this year (Chappelle in LA, Louis CK twice, Ali Wong, Laugh Factory Las Vegas), and with their kind of comedy you have to listen to their whole dialogue and delivery to really get what's being said. Pick-and-choosing choice quotes will always be taken out of context.
One thing I can say about Dave's recent stand-up: when I saw him do his show in LA he had a bit about social justice warriors...what he criticizes about them is that they keep having hyperbolic knee-jerk reactions to everything. He emphasizes for them to simply 'pace yourself.' Take a step back and think about it. Pick your battles. It was a common theme in his show back in March.
That said, for now I can give Dave the benefit of the doubt and take The Observer's original report with a grain of salt.
