Depends what someone is distressed about. Some folks, get a tad thrown off, when others have to misrepresent science, to uphold and protect a personal faith belief. This just bothers them as they have a thing about accuracy.
In regards to some Christians though, it is really entertaining, to watch the defense mechanisms and scramble mode ensue, when they are presented with verifiable evidence and facts, that may contradict a personal faith belief.
One real good measure though, of intellectual honesty is; is someone willing to admit they could be wrong, or are capable of learning new things that could change their position. From my experience on this site, Christians are far less likely to admit there is even a one percent chance their specific faith beliefs are wrong, or they may learn something in the future, that would alter them.
When one fails to acknowledge there is any chance they are wrong, this is a big clue, they have some deep insecurities about the belief.
