There are many good arguments for ignoring or even opposing Ron Paul on grounds that he is a Republican, and that supporting Paul is to support, indirectly, the modern Republican gang.
But this isn't my reason for opposing Ron Paul. I oppose him on policy. Not tiny little issues like DOMA or Abortion or this-and-that. These are core policy issues that drive me to oppose him openly, verbally, and with every fiber of my being.
And I'm a Libertarian.
1. Civil Liberty.
Ron Paul says he is for civil liberty. This is not true. He believes in privatization of everything, and that private businesses have a right to discriminate for any reason whatsoever. If roads were privatized, the "road company" could deny access to travel for any reason. This is not civil liberty.
I am all for a reasonable discussion about private employment rights. They certainly don't exist today. And it's the lack of such protections that made ideas like Unions and Affirmative Action important parts of our history. It would be nice not to need unions or affirmative action. Paul would like to simply get rid of any protections whatsoever. This is not civil liberty.
It is good that he argues against prohibition. It is good that he argues against arrest for non-violent actions. This doesn't means he stands for civil liberty.
2. Monetary Reform.
Ron Paul says he wants to "End the Fed". He says nothing about ending fractional reserve lending (banking privilege, aka "fraud"), or ending the privatization of currency that exists NOW under the central banking system. He just wants to end the federal bank and let state banks do what they want.
He also claims that a gold standard is prescribed in the US Constitution. It is not. In fact, a gold standard is arguably NOT constitutional. William Jennings Bryan tried to oppose the central banks prior to 1913. Ron Paul is certainly no Bryan.
Real monetary reform is an important issue for me, rooted to American history and our national struggle, our world struggle, against enslavement to central banks. I will not allow him and the Austrian School to crucify mankind on a cross of gold.

3. Social Welfare.
Ron Paul says he wants to end Medicare and Social Security, all activities that aren't authorized by the constitution (in his mind). This is crap, and his followers mimick this drivel on every facebook and youtube post in America.
The only argument against social welfare is taxation. Resolve the tax issue and there's no reason not to include social welfare (i.e. safety net or whatever) into public policy.
Never mind endless arguments over USC Article 1 Section 8. Never mind trying arguing that, by definition, Medicare isn't "socialism". They will not budge, and raise their bible in hand as if they are the only ones privy to the Holy Word. Idiots.
4. Foreign Policy.
Ron Paul says we should never involve ourselve in foreign affairs. He's the conservative who wants to adopt an isolationist foreign policy. While I agree to a large extent, it is a very naive view to think that the US has spread the plague of world poverty and oppression.
There are sound reasons to intervene in the "affairs" of other nations. This should not be done by volunteers as it has with the IRA or in the Spanish Civil War. It should not be done by corporations hiring death squads in El Salvador or Columbia. We should not be a nation of mercenaries.
And I will not trade "End the Wars" for "End Welfare". They are two completely different issues. If people can't see that, they are probably Ron Paul supporters.
5. States Rights and the Constitution.
This "Revolution", the R-Love-ution, that Paul is building is not the 1776 version; it's the 1861 version. The oppression of a State is no different than the oppression of a Federal government. And in cases where States are in the wrong, it is the responsibility for the other states, through the Nation, to resolve the problem.
Rights are universal, to all human beings. Sovereignty is of the Nation, not the individual States. The South may be rising again, but I will be on the side of Union.
These are not simple policy differences that I should simply ignore in exchange for some higher "message" or "movement". These are core issues that affect the millions of people being oppressed by bad government.
Government is not evil; corruption is. When government is controlled by plutocrats, by a covert aristocracy, by corporations or banking interests, then it is corrupted.
I am convinced that the whole of Ron Paul's C4L movement exists to pull young and poor people into the Republican fold, to offer pie in the sky (like ending military intervention and legalizing pot) in exchange for moral, grassroots support of deregulating and removing taxes from the richest 1% of Americans (i.e. Republican policies).
Libertarians need to get their heads out of their asses and understand truly who they're supporting and what they're doing. In my opinion, these Ron Paul supporters are fighting for the wrong people. They're certainly not fighting for me.
