Being so agressive over someone else’s cluelessness is not OK. Imagine if teachers in schools were that punitive over children solving problems wrongly, kids would never have learnt anything.

I didn’t claim that politeness makes one’s assumption correct all of a sudden, I was pointing out that it was an indicator that OP was not being trolled and could’ve presented their disagreement not in the form of drama, enlighten the other side of the discussion and have a nice day.
