The present definition in the article is Libertarianism is a philosophy advocating that individuals should be free to do whatever they wish with their person or property as long as they do not infringe on the same liberty of others  In order to understand what this sentence is saying we need to know what same liberty means At paragraph  I break the sentence down into its component parts substituting for the same libery what is meant by the same liberty  If you believe my substitution was wrong then please do your own substitution for the words the same liberty  The sentence as it stands does not define the libertarian right ie libertarianism because it permits anything to be the right because it is using right to define right  In other words under the present definition A can batter B if B is gay provided A is willing to let B batter Aif A is gay  This is not permitted under libertarianism so the present definition doesnt work
