Perhaps we have a miscommunication here.
First of all, I agree with you that photographers and bakers should be able to serve the customers they wish. This is one area in which I'm quite conservative.
But the main issue is that simply by advocating for any government for any purpose at all, you are, by definition, forcing someone else to accept your beliefs about how things should be done. It takes taxes to fund government, and police with guns to enforce laws, which means that even if all you want the government to do is military, police, judges, roads, and NASA, then I have to accept the authority of those agents, and pay taxes to pay their salary.
But if you want to transcend the "gun pointing" involved with all government and get into actual policy, I'd say a lot of bad republican policy is at the state/local level, but against people without the means to efficiently just pack up and move. The idea that a cop could ask to see my ID on the street is asinine to me. The idea that pollution can happen at such a rampant rate, and that any solution is "government-forced conservation" rather than a legitimate transfer of wealth based on socialized costs, is equally annoying. Pot being illegal, police being over-bearing, our food being genetically modified (by the private sector with limited government interference)... to name a few more. But really, I'm not all that liberal. I think most of the things that our government SHOULD do, it is already doing, or at least moving in the direction of doing. Social safety nets could be stronger in some areas, but I think they are fine. I just choose to debate those who would dismantle them, or wish to assert things about them that simply aren't true. There are areas I'd even pull it back. I think Medicare for all would be a superior healthcare system, but I think we've filled some of the holes relating to insurability... and I happen to think a lot of the Republican arguments around the healthcare market are utterly bogus.
And the reason I, personally, don't think there's much of a difference between parties is because they always change their tune when the other party is in office. Obama wants to return taxes to Clinton levels, and levels lower than most of the 20th century, "he's a bleeding hear socialist." A democratic congress enacts a health care law that is essentially what conservatives suggested (and Romney passed) in the 1990's and 2000's, respectively? He's "taking over 1/6 of the economy." Obama enacts a stimulus package filled with plentiful supply-side tax cuts and blank-check aid to local and state governments to direct, and "he's spending us into oblivion (never-mind the stimulus package is an infinitesimal amount of our current nat'l debt). Libs go after Bush & the Iraq war to a much larger degree than they ever would have gone after one of their dems. Republicans worry about the "forgotten middle class" and "high effective tax rates" and "too much government bureaucracy," but then want to means-test SS (beyond what it currently is), which would add a lot of complexity to it.
But all that is just details. Government, by definition, governs over a region, and therefore consists of some people's views being enforced, at gunpoint, over other people's views. Even if it is just to fund a military, and in some ways, ESPECIALLY so... if that military decides that I look like a good soldier
