With the recent implementation and roll out of the ACA, the wingnuts are in full entitlement mode, claiming the law infringes on their liberties. Let's just call it what it really is: Privilege. They can't stand the fact that people other than themselves are starting to gain access to privileges they've always had for simply being born into the right circumstances.
This can be said for virtually every social gain in American history from the Bill of Rights to the Civil Rights and Voting Rights acts. They've fought every bit of progress made, especially in the last century, and when it comes to economic issues at least, they've succeeded in dragging us back to the roaring 20s kicking and screaming with the past three decades of organized theft.
The other reason they're against that progress is also a simple one: They've never had to deal with the shit that we have. Of course, the reality of it all differs from person to person, but it's clear that anytime we want to make our lives a bit more bearable, you can bet your ass that the wingnuts will be in full force to make sure it never happens.
The defenders of privilege will do all they can to keep all they've stolen, even if it means destroying the very country they claim they love in the process.
