You’re right conservatives are much more charitable than liberals, and they do so voluntarily, they don’t need the government to force them to help their neighbors.
In the aftermath of the the Katrina disaster, I was posting on the Seattle Times web site about the hurricane. The libs were going nuts blaming Bush and whining. I told them that my husband was preparing to go to New Orleans to help out and asked them what they were doing to help ameliorate the situation. Democrats whine, conservatives act in a crisis.
Also, if I recall correctly, in cases of public giving in a crisis, a recent study showed the highest per capita amount donated came from RED states, most notably the Deep South.
