They're on the same level insofar as it's been deemed serious enough by someone to put on this list. Just funny to see it on a list filled with ethnic slurs and a couple disability slurs, looks very out of place to see an extremely-online insult alongside slurs with tons of historical baggage.
Does it really surprise you to see an extremely-online insult being included in a black list for an app for extremely-online people? I genuinely can't understand the confusion.
