Refusal to believe other people genuinely believe in other religions
Did anybody else experience members or preachers essentially acting like other religions don't genuinely believe what they believe? I remember sermons where the preacher was heavily implying that Muslims don't actually believe in Islam and Hindus know vishnu isn't real and secretly "know in their heart of hearts" that Christianity is true, when that wouldn't make any sense at all. There's no motive at all for something like that and that damn near requires conspiracy theory tin foil hat level of insanity.
This is furthered to me by the many sermons we had on "what other faiths believe and why it's wrong" where they very obviously misrepresent what those faiths believe to make it seem silly and ridiculous.
I suppose they have to tell themselves that because then they'd have to contend with the fact that other faiths can be just as convinced what they believe is true as they are and that due to that they can just as easily be wrong and another just as easily be right. Opens up a type of introspection that can very easily lead to deconstruction, so it's easier for them to convince themselves they're the only ones who believe that strongly and that makes them special.
