Is this just an inconsistency or what?

My standards for a joke comment is if it is written with emojis, some inconsistency uses for uppercase and lowercase letters, the word "sarcasm" written in the end inside parentheses, and/or a comment so ridiculous and/or exaggerated no people with common sense is serious with that comment. But then there's this:

A: You can't possibly posted that comment unironically.

B: No, I'm serious.

A: Well, then that controversial comment of yours definitely says a lot about your moral code.

B: R/whoooosh
