One need not be a Capital-L libertarian in order to be a libertarian in belief and action. Eventually, (I don't know how old you are, but it may not even be in my lifetime) small-l libertarians will be the core of the republican party. Even some Tea-Party social conservatives have been making some libertarian noises with respect to social issues vis-a-vis the proper role of government, so we will see. The Bush/Obama big government spend-o-rama may serve as the best cautionary example of what not to do we could've hoped for.
