I you're being overly simplistic:
* Smoke weed but not tobacco -- perhaps means you get new freedoms of legally doing drugs, but the government wants to regulate how much tobacco you consume, and not completely stop you from doing so.
* Censure from saying hateful words -- since when? There's such thing as first amendment, but it doesn't guarantee that no one would think you're an arsehole after you exercised it.
* There is no health benefits of eating fast food, there is an obesity epidemic, government must regulate it. See tobacco, catalytic converters. No one is saying that you'd be prohibited from eating it, but all the government could do is: make it more healthy, make people eat less of it, remove corn subsidies, and in general be more proactive about it.
* Alcohol is regulated soda isn't, soda is almost just as bad for you (see alcoholic cirrhosis vs. fatty liver disease). Also it's partially government's fault that we decrease our intake of fats and instead started eating really unhealthy carbs. Also I recommend watching this video that exactly explains why soft drinks, and sugar in general are really bad -- http://www.youtube.com/watch?v=dBnniua6-oM .
* To the credit of democrats I'm yet to see anyone who doesn't agree with them to be called 'terrorist enabler' or 'traitor' or anything like that.
You also generalize to a great degree, there's liberal wing of democrats and there's a conservative wing of democrats, there's constant infighting. Name one elected republican politician except Ron Paul who is for personal freedoms? I dare you.
I hate this false equivalences, yes democrats are pussies and are bargaining away too much of their principles, but republicans are batshit crazy at this point they have no principles, have you seen new republican manifesto -- all empty slogans. What is common here? Now you propagating an idea of being complete cynic and not doing anything about the situation, and feeling at the same time; that's just counterproductive.
