“It’s like black and white,” yelled someone from the crowd.'
It's not like 'Liberals hate Real Americans' needs rebutting but...
Statements of the form 'All X are Y' -- which is pretty much the definition of a prejudice. And 'hate' is a strong word. I'm sure there are liberals who might use it in response to statements like these, but I think they're in the minority. True liberalism counts tolerance as a defining principle, which would mean you can respectfully disagree with nearly everyone.
Second, Liberals work and achieve. The more educated one is, the more likely one is to be employed and have the tools for all sorts of achievements. You're less likely to work with their hands, but there's loads of white-collar conservatives too.
I think a more accurate way of putting would be "Liberals are infuriated by cynical, calculating Right-wing demagogues who seek to exploit the ignorance and paranoia of others to achieve their own selfish goals."
