You stated one of their core doctrines, something they’ve been loudly preaching for as long as they’ve existed, as though it was something they disagree with and had never even considered. Can you blame them for a bit of exasperation? For wanting to simply downvote-and-disengage from someone who makes up falsehoods about them and then gloats about how it annoyed them? Life is too short to tilt at windmills.
It's a "tool," it's a not a "magic window into absolute truth."
Tools can be good for a job, or bad. Carry on.
