I thought he was just trying to be funny, but if he genuinely doesn't like actors, actresses, directors and producers or approve of the way they accept awards, then why was he hosting The Golden Globes Awards show in the first place? And why tell them all to "f*** off"? He was the host, and should know better than anyone that it will just have to be censored anyway... so what was the point of saying it? It also seemed a little disrespectful to the people who paid him. He was paid by NBC to be there. They pretty much only have one rule... Don't cuss.
Also, I don't care about him telling a crowd full of rich people that they are in no position to lecture anyone... but as to whether or not they "know nothing about the real world"? Well, that depends on who he was talking about. They do not all come from privileged backgrounds, and it's wrong to make such a blanket statement to an entire crowd of people. Some of those people came from nothing and truly are self-made. I would cite Jennifer Lawrence's upbringing as an example of this.
