Or, the more realistic explanation, which is that you were in the middle of a heated discussion, said something that wasn’t reasonable or appropriate, got called out on it by multiple people, then backtracked and pretended you were joking the whole time. Which you clearly weren’t.

There was no tone shift. There was no /s. There was no “non-serious” tone there. You wanted to call into question their credentials, and found the most idiotic thing you could and ran with it.

The fact that every single one of your replies is serious and aggressive in tone does not help your case. Obviously that one paragraph is the sole exception, obviously.

Next time, just take the L in stride.
