If I say, the earth isn’t a perfect sphere and that actually it’s a bit oval/elliptical (or whatever or supposedly is) and then someone answers all pissy and asking me to prove it, do you really think I’m likely to help them understand my position if I find them rude and annoying? Most people that genuinely want to understand others’ point of view don’t say things like “or was that someone else’s fault?” They say things like"can you explain why you think that?" or maybe “I’ve been thinking xyz, why is it you think abc instead?”
