Our troika of fascists........Hitler, Mussolini, and Franco....all USED Christianity............but would anyone observing them cite them as true Christians.

What difference does it make? A better question: What Christian has not used Christianity? Or another: How would we decide who was the true Christian? We cannot use the Bible. Christians are always telling us non-believers that we cannot understand the Bible until we get the spirit. So ultimately it comes down to personal revelation, the most subjective measure of "truth." IOW, by Christianity's own admission there is no objective measure of true Christianity.
