Democrats, Republicans, What's the Difference? Part 2

O.k., so Democrats and Republicans are different, but surely they can compromise and make progress.  Ok., how about we review some of the things people think compromise should be found on:

Social Security:
Democrats want Social Security to be strengthened.
Republicans want it gone.
How exactly do you compromise in this instance?  If you're Republicans, you claim that you're trying to strengthen the program by reducing the benefits (to maintain the program in the long run even though it hurts the underlying point of the program) or by privatizing the program (essentially, hand all that money over to investment bankers to play with).  If you're Democrats, you see through both options for what they really are since you've been hearing Republicans rail against the program for decades.  So... how do you compromise on something so black and white?

Environment:
Democrats want to make the air quality better by moving to electric cars or other alternatives
Republicans like oil...
So we compromise and instead of slowly improving regulations on cars so that they are more efficient and less polluting while maintaining gas cars rather than rapidly building up our electric-car infrastructure and enhancing our public transportation, we keep everything exactly the same (or let them deteriorate).... except California... cause they're concerned with such things as air quality.

Guns:
Democrats don't like guns in the hands of the public because they are concerned about public safety.
Republicans want guns in the hands of the public because it's all about freedom to them.  Freedom to have a gun is as important to them as freedom of speech and significantly more important than freedom of religion.
Ok, so in this case, let's start with the starting volleys for compromise:
Democrats compromise by saying that we only ban new sales on guns, not take any away by force
Democrats compromise further by saying, let's not even ban new sales on all guns, let's just ban sales on semi-automatic rifles... we've already banned automatics so this isn't something that's totally outrageous to consider.
Democrats propose that we ban the sale of high-capacity magazines... we did this in the 1990's, the world didn't fall apart.
Republicans counter these compromise options by saying we don't do anything about guns or any gun parts.
Remind me who's unwilling to compromise?
