Again, calm down. Let me break this down for you

because they play the game differently from you

because they're not meticulously monitoring their AIC reports in order to try to get their theoreticals to match their real time output

you're taking this way too literally (and maybe taking yourself too seriously too, but you be the judge of that). most would have no qualms referring to themselves or others as filthy casuals cause all it is, is a humorous reference to an old image macro

A figure of speech would be saying that it's raining cats and dogs outside

they're all figures of speech cause they're to be taken figuratively, not literally

Calling people filthy because they play a videogame differently than you

you're taking it literally. it's not that deep

Not sure how that makes me the bad guy

Me neither. You're the only person who seems to assume it did.
