I feel 'tribalism' is a better term for this sort of thing than 'herd mentality'.'Herd mentality' covers the relentless churn of consumerist fashions ('OMG must buy teh new hawt thing 'cos everyone else is!!!111one') nicely; but 'there's an arbitrary difference between us and them, let's bash the shit out of each other' distinctly reminds me of that scene from the start of 2001 where the apeman tribes... bash the shit out of each other over an arbitrary difference between them.
Your sentiment's spot on, anyhow.
