A Christian is one who follows the teachings of Christ. One can claim to be a football, but that does not make it so. If you can find where Christ said to start shooting police or did so, then we have a basis for the first part.
A Christian is either one who believes in Christ as divine or one who follows Christ's teachings, depending on which definition you adhere to. You'll find both both as standard dictionary definitions.
The problem I have with all of this is that Christians seem fond of defining wrongdoers out of their religion, more so than other groups do. If a given act is not in accordance with bibical teachings, who is to say that such a person is not a Christian, instead of saying that the person is a Christian who did bad things, or a Christian who, in this case, failed to follow the teachings? Every religious person strays from religious teachings, as those teachings are interpreted by others adhering to the religion, at times. Who is to say when a given person has strayed far enough to be defined out of the religion?
Christians are big on allowing perpetrators of ordinary "bad acts" to "repent." However, when a person does bad acts *in the name of Christianity*, the usual response is that the person is not a real Christian. Why all the sudden is that person not a Christian, instead of a Christian who is a wrongdoer and who can repent? A child molster can be a Christian who strayed and can repent, but someone who commits an act of terrorism in the name of Christianity is just not a Christian?
The reason for the inconsistency is obvious - because people who commits bad acts in the name of Christianity tend to tarnish the image of the religion. Accordingly, it is convenient to define those people out of the religion. This seems to include large scale historical events, such as the crusades and the inquisition.
It may well be appropriate to point out that a Christian terrororist is not following the teachings of Christ when he commits a terrorist act, but saying that the person is "not a Christian" is just too convenient; too pat.
I remember when Baruch Goldstein shot up that mosque and killed all those people. It sparked a lot of anti-semitism - people generalizing from his behavior to the behavior of Jews in general. The response from Jews was to condemn the act, and to oppose the generalization; to say that his behavior was not typical of Jews. It was never to say that Goldstein was "not a Jew." Yet in Goldstein's delusional mind, he committed this atrocity in the name of Judaism. The temptation was there to define him out of the religion, I suppose. However, it seems to be more common with Christians to get very self-righteous about who does and does not belong to their religion, and to define people out of the group whenever it is convenient to do so.
Suppose a liberal went out and shot up a tea party rally. If I were to say, this person is not a liberal, because liberals believe in non-violence, how do you think that would fly around here, hmm?
