1. LOL. That roughly translates as "if I go into specifics, I will get my ass handed to me, so I will stay comfortably here in the realm of generality where I can deflect and dodge rather than discuss."
2. Again, nothing is necessary. You are using that word disingenuously. The difference between what you support and what you don't isn't a question of necessity. It's that you prioritize things differently. You're trying to shoehorn a question of values into a question of liquidity, and like most people who try that particular stunt, you're doing a bad job.
3. As for government programs I don't support, I'm in agreement with Cato on this:
Much of what the USDA does should be scrapped. And most liberals agree. So you can take your "we like government regulation for its own sake" and shove it up your ass.
