there you go. the tagline for liberalism is dead on, just 1,000 years too early. In other words we aren’t anywhere near evolved to think that the majority of liberal policies do nothing but exascerbate (sp) the condition they attempt to remedy. One way to beat them is to attack them using the culture of blame they so cherish.
Example. I’m waiting to hear who’ll be the first one to get smart and start suing the ACLU and the others who actively work against the immigration laws. I’m thinking someone may have a lawsuit here when a loved one is hurt or killed by an illegal. Using the trial lawyer shotgun approach to assigning blame, there should not be a person left standing who won’t have to answer to the process should this guy have a record. It’s got to be like enforcing the drunk driving laws. Any more you can’t let anyone go, whereas in the past famous or connected people might have be given a pass at the station or in the field. Why? Liability should they go out later and run someone over drunk. Same same.
I'm disagreeing with your notion of "evolved" humans as in somehow more advanced or better. If you changed human nature so as to make leftist policies practical, you would have people unrecognizable as humans--drones for the state, in effect. Karl Marx's "New Man" never emerged and never will absent the genetic engineering of the entire human race to be Eloi's.
The tragedy of liberalism is not that it is before it's time. The tragedy is that it is wrong, impractical and immoral and should never have come into being in the first place. It should have been laughed out of the room before it ever got loose to mess up billions of lives. But, fallible as always, human nature rushes to embrace that which is doomed to fail because of human nature.
