>I don't believe I was particularly aggressive.

"You don't know what you're talking about" is aggressive and rude; like you're calling them stupid. "Actually, I don't think that's right", along with some, "Can you clarify?" is not aggressive, and welcomes them into a conversation.

>I called them out. That's how it should work.

There's a way to do that constructively. See above.

FWIW I thought your comment was aggressive and borderline rude. Being right and being polite are not mutually exclusive.

To be fair, I did look at this in the best light possible and took your overly aggressive tone and hanging your hat on a scriveners error like putting a “2” instead of whatever other number when it was clear what the poster was talking about to be an EQ gap on your part and not malice.
