Earlier quoted context omitted.
I agree with the parent, you’re argument almost appears disingenuous to the point of looking like a troll or bait. This perspective is substituting any belief with a religious belief which is a false equivalency. It’s unfortunate that the grandparent is the top comment right now.
Can you share profound beliefs that you don't believe are religious in nature? I know trivial beliefs e.g. today was 85º – we can agree that calling those religious would not be useful.
Using your original logic, -any- belief can be religious in nature. “Today was 85” -is- religious from your original position because perhaps people ritualistically check the weather every morning like a prayer. The weathermen are like priests disseminating knowledge, and small talk is used to find other weather checker cultists.
It does not matter what belief Id offer up, because it will match your original definition because your original definition is so broad as to be meaningless. Other comments have already said this in fewer words. If you are unable to identify what it would look like if you were mistaken, then you shouldn’t be confident that you are correct. So how could someone identify the difference between a secular belief and a religious belief?
