Those Christians would say they are the true Christians, cite sources to prove it, and call others untrue Christians. The no true Christian argument reminds me of ‘true communism has never been tried’ when a Marxist tries to escape the challenges of communist issues. Those communists who were in power would say the are true communists, and those saying otherwise are communist counterfeits.
Besides, I find your arguments to be very much like the intolerant Christians who cause misery for others. Not saying you are like those who used it as justification for killing the heretic, but you have a negative view of and appear hostile to anyone outside your branch of Christianity. Including other Christians on here. It’s this kind of polarised view which can cause tribalism and issues.
