There is only one rebuttal to the claim that political conservatism is un-Christian, and that is to say that while Christian conservatives are as concerned about the less fortunate as liberals, this concern should be rightly expressed through private, as opposed to governmental, agency. Such governmental efforts invariably, the conservative says, do more harm than good and undermine freedom.
The above is an interesting, and debatable position.
Ann Coulter, however, criticizes private efforts to respond to the Ebola virus in Africa. This strikes me as hopelessly unbiblical.
