Yeah, happens in RL too.
Because people love to form in-groups and out-groups based on their own perceptions of who they like.
"He's in Carelia... but he doesn't sing the Carelian national anthem in his messages... so he's not REALLY from Carelia."
"He's in Carelia... but he has a character in Suville too... so he's not REALLY from Carelia."
Are all just a way of saying, "I dislike him– I will invent new category restrictions to exclude him."
Poor examples IMO, but yeah.
