I wasn't being rude (At least I don't think I was? I'm sorry. Tone is difficult to communicate sometimes and my brain is fried) I was just asking if they had any evidence to back up their claims?
If it wasn't intended, then I am the one who should apologize to you! I read it as snarky, but tone is notoriously hard to get across through text. (And I've never been particularly good at figuring it out myself.) My apologies. :-)
