CINOs don't "confuse Republicanism with conservatism." They are, by definition, simply contemptuous of conservatism (and conservatives).
"Moderate" Republicans are nothing more than social liberals who nonetheless hunger for the occasional tax cut or three.
What surprises me about these people is the hostility they exhibit. They seem to take it as a personal affront that some conservatives won't vote for Romney because of Romney's politics. There are no good choices for conservatives in the candidates of the two major parties. It is a tough choice. Should a conservative vote using pragmatism or principles? I've made my choice, others can make theirs. Respect my choice and I'll respect your choice, even if I don't agree with it.
