Even morality cannot just be reasoned into, since moral "shoulds" don't follow from factual "ares" (check Hume's fork, or the "is-ought" problem, for an easy explanation). Every belief of these natures is something you either take or not. And "religion" is doing a lot of work here and is inappropriate. I understand dismissing many belief sets and ideologies because they contradict either reality or your own moral codes, and I also understand having a bad after taste for all beliefs because of a negative experience with one (I felt this way myself for about two decades!), but the latter simply doesn't follow logically. And to each their own, of course.
