There's no such thing as a true Christian. Protestants don't think Catholics are true Christians, Catholics don't think protestants are true Christians, the Westboro Baptist Church doesn't think anyone but themselves are true Christians, and other Christians don't think that the WBC are true Christians. Ask any of them if they're true Christians and they'll affirm it, but ask other Christians who disagree with them and they'll say no.
Or if we're going to argue that there is such a thing as a true Christian, then it's someone who exemplifies good, moral, Christian living, but as soon as they fuck up and do something bad they're no longer true Christians.

Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
