As an individual who is, on some issues (fiscal, for the most part, although not close to all) conservative, and on others libertarian (social issues, and I identify socially neither with the D’s or R’s) I think I can shed some light at least on my opinion.
First, I don’t think taxes are theft. They’re part of the social contract of living on our society. Second, I don’t think the government is tyrannical. Although just because the majority are represented doesn’t mean that a government is without tyranny – this is why the expression “tyranny of the majority” exists. It’s one of the things that the constitution exists to prevent.
I do think, and this is often where the ideas of mine and others get confused, that federal governance is in general bad. Not because they enact bad policies (though they sometimes do), but because those policies shouldn’t necessarily be applied to everyone in the country. Drug laws are a perfect example of this.
You have far more voice in your state government than your federal one. And you have ever more in your local one, and it’s my opinion that whenever possible laws abd governance should be done on as small of a scale as possible, in order to best tailor those laws to the reality of the area their in.
