One of my recent characters was your classic racist greedy dwarf. But it was her greed that knew no bounds so the racism part rarely came up because why would they be an asshole to a bunch of adventurers helping them get rich beyond imagining? Why would they be an asshole to the people giving them a ton of money for running around to save the world? It mostly manifested when we’d get minor encounters and I’d suggest we have better things to do than help out these elf randos, or during combat I’d be on top of healing any dwarves but drag my feet just a little for other people. It’s important that your character flaws still function within a group and that you’re not using them as an excuse to force solo play or excuse being a dick irl
