Libertarian Positions

[mbm30075]

I've been reading a little bit lately about the Libertarian political platform, and a lot of what they have to say makes sense, but I was hoping that some people here could give me a better sense of some of their beliefs:

1. It seems like a lot of Libertarians would agree that taxes = force = theft = wrong. Does this apply (in their opinion) only to income tax or to all taxes? If we give up paying taxes at all, how do we have roads, water, sewer, etc...?

2. I've seen that a lot of people seem to be sort of "live and let live" on the homosexual marriage issue, but what about the following statement?
"Get the government out of sanctioning marriage at all."
I mean, if marriage is a spiritual union (as most people would agree it is), let's let churches deal with it. It seems like legal marriages only exist for governmental control, right?

3. How extreme does the Libertarian agenda get? Are there some non-violent anarchists (for lack of a better term) out there that want literally NO government? Do Libertarians see government as a necessity?

Can someone give me a synopsis of the Libertarian utopia?

Thanks!
