Why would anything he said be unacceptable? Because it makes conservatives and libertarians uncomfortable to think about? Because it doesn't involve working people getting on their knees and accepting whatever managers and corporate leaders decide upon? There is indeed a war on the working class and organized labor going on in this country and it's a good thing someone's talking about it.
I'm also glad somebody is talking about it and isn't afraid to use a little hyperbole to get the working people fired up.
I think the Tea Partiers and white collar Republicans are terrified because the "REAL 'MURICANS" aren't actually the people sitting on their electric scooters wearing funny costumes and telling government to stay out of their medicare... but the people who actually work installing their plumbing and electric lines and providing them high speed internet and paving the roads they drive on and teaching their children and keeping the streets safe and putting out your house fire and caring for you when you are sick...
They should be scared of what happens when you push "REAL 'MURICANS" too far. They tend to give in for a while... and then snap. And they won't be wearing tri-cornered hats and complaining about the deficit. They'll be the ones who finally make a charge at the Tea Party only to watch as the Tea Party, with all its grandstanding and big talk, cower away like the spoiled adult children that they are.
