Why do you call them 'liberals' instead of COMMUNISTS? Are you afraid of offending their emotional-sensibilities?
These people are communists, pure and simple and I think we should stop coddling them. Some of them will admit they just want to consume more than they produce -- it isn't their 'fault' that they aren't capable of producing enough to meet their gluttonous desires! They rest of them haven't the intellect to rationally deduce, much less explain, what they want -- they proceed on an intellectual level scarcely above that of the coyotes. So, communists consist of Morlocks and Eloi.
I liked your idea of an island for violent criminals. The communists have a criminal mindset, whether or not they have the courage to actually attempt violence. We should put them all on a island together and let them consume as much as they want. That should end well for the rest of us.
Humans deserve better.
I have come to realize that men are not born to be free. Liberty is a need felt by a small class of people whom nature has endowed with nobler minds than the mass of men. -Napoleon
