And that, is a bunch of bull.
I am a Libertarian and, in my experience, the Libertarian point of view is more along the lines of "It's my (and your) personal decision on whether or not to share".
*Enforced* sharing, under threat of duress, punishment, fines, jail sentences, etc. *is not* sharing. Taxes for things that pay for things or services that a particular individual never uses falls into the category of *enforced* sharing.
Get the government out of things it not constitutionally mandated to do, cut the size of government, put more money in people's pockets (as a result) and let them decide where and how they want that money spent.
The U.S. Federal government, in particular, is and has done a piss poor job spending your and my money. Oh, and our kid's and grand kid's money too.
