Rude.
What is rude is your reading it like that and taking offense where none was intended.
“Rude.” People aren’t generally like that here. Welcome!
Sorry, I read the poster’s message as “WE, unlike you, don’t require proof so that’s why we’re not making a big deal of the Flynn thing, you lately-arrived uninformed person.”
Rude.

You’re right. Had I written that or intended that, it would have been rude. I regret the misunderstanding and will try to choose my words more carefully in the future so as not to prickle anyone.
