Farfetched(?) example:
Me: Maybe I'll start using Intelligence instead of Dexterity for initiative rolls. Anyone else tried it?
Some guy: How dare you. That isn't fun, it can't be fun, and other people will wrongly assume it's fun if I remain silent. So in this essay, I will address everything that is wrong with your idea, with considerable emphasis on your poor understanding, your wizard fetish, and your obvious hatred of rogues.
Me: Yikes. (clicks ignore)
Also me: Why is everyone yelling at each other about rogues and wizards? I wanted to talk about initiative.
