There's a reason why both Class IV and V rules are unremovable yet distinct and the reason is that one, while obscene, doesn't actively prohibit gameplay. Someone calling another player any range of racial epithets is not the same as outright denying that player the ability the play the game / ruining their RP experience by MRDMing, propblocking them or any other range of Class V offenses.
Likewise, whether or not players who actively say racial slurs participate in MRDM, NLR (which isnt a Class V offense) or LTAP doesn't mean we can pile all of them into the category. That would downgrade the severity of a Class V offense and outright remove the existence of a Class IV offense which basically encompasses rules against harassment in the first place.
tl;dr - Sure, racism & hate speech can make someones time on AtomicRP unenjoyable but that's the reason why we have it so it's a permanent stain on someones record here along with the 1 day ban to decide whether they want to even come back or not and play nice with everyone else. Noob & Wilkers did a pretty good job outlining the rules when they did so that they have purposeful distinctions.
