Is this an either/or question?
The right to bear arms is often (deliberately) misrepresented in the US. There are some that translate it to "I can have a gun if I want one".
The founding fathers almost certainly did not mean that, they thought (and the wording of the original amendment implies) that such a right was necessary for the defence of the state.
Every US citizen should be entitled to "free at the point of delivery" healthcare, but the way this has been/is being introduced is a real botch. I think that Obamacare is a good and sincerely-intended system, doomed to fail because of conservative resistance. A pity.
