So, yeah I appeared a bit strange in that comment, but my clarification is that 40 years of experience among people has taught me two things: the probability of disastrous interactions is very high when the other person is not religious (in the truest sense, like Khabib the UFC champ, and not nominally like some people)...
In this, my comment may help others, in fact. I have not become a cynic for no reason. Time and again, being an optimistic, cheerful and kind person, I have been betrayed, mistreated, and otherwise caused to suffer by barbarians who only look human. My contention is that sooner or later, others will face the same--unless they lived in societies where true morality and ethics as enjoined by Islam is being practiced and taught. Even there, you will get your share of crazies and strange people who are religious by name only, but the probability of them being harmful is way lower.
