[@Diggerton] It's not 'acting a different way'; it's coming from a certain culture and then... having absolutely none of those cultural values and generally being their opposite for no reason. Take a typical dwarf, and then making them a teetotaller hippy who shaves and doesn't care about his people. Or the Drizzt clones.

Or badly written foreigners in series, who act like natives with a funny accent.

It's not uncommon for people from a certain culture to go against its values; take NEETs in Japan which come from a very hardworking culture or people raised in highly religious communities and become atheists. It's definitely not crazy for someone to go against cultural values.
