More levels does not, by itself, mean more of anything else. In one system you can get fifty different skills, features, traits, abilities, etc at each level and in another you get one attribute point increased by one at each level up. It’s one of those things that is absolutely meaningless without the context of a lot of other information.
That said, for the joke, Asian games tend to use a greater number of levels, either with smaller increases in power or they just don’t cap anything and let the numbers get bigger and bigger with little or no functional difference as long as you’re fighting things scaled to your level. A little stat boost every level then a special power after ten can be the same as one level where you get all that without the other nine congratulatory dings that don’t really mean much.
The reason many still associate D&D and anything else remotely related to it with fat, basement dwelling, socially inept virgin incels is because those people actually made up a significant percentage of the original following of the hobby. Because it’s founders were only a half step away from most of those descriptions in many cases. And anybody that insists otherwise is either willfully ignorant or, more likely, angry at being called out by association because they’re the same.
So either get over it or go join the people that still insist that the confederate flag is anything but the war banner of a rebellion raised as an attempt at preserving slavery as a legal institution. You have the same mindset and validity as they do on this matter.
Yandere needs the clarification of burning your character sheet from the other game, then shackling you to the table for theirs.
Also thugdere’s stance is grounds to have them committed to an asylum for the criminally insane for life. Or just euthanized as a ranid animal, depending on the jurisdiction.
