One I have heard when pointing out that I was a Christian before I realized the extent of my self-deluding thinking which I was subscribing to, is that “you were not a true Christian or a true believer”.(no true Scotsman). This is of course an absurd deflection from the fact that not one single piece of evidence has ever been provided that can demonstrate the existence of any God, as well as being a logical fallacy.
The arrogance of all of these pronouncements is breathtaking. The fear of being wrong is so strong in some people that no logical argument will get through the myriad of non-nonsensical thought processes.
