The thing that really grinds my gears about D&D 5th Ed is you're meant to believe that some fucken bright red humanoid with horns, red scales, talons and a tail can walk into a shop or a bar and not get the full screaming/pointing/pitchforks/torches routine.
Devils and demons *are a thing*. They are known to cause murder and mayhem. How is Dave the sheep farmer meant to know the difference between a Devil and a Tiefling? He can't.
Fucken stupid game design of the gayest order.
