I don't know guys, but I think you can hate a people in a way that doesn't make you want to kill them every breath you take or even turn you crazy over a while. This, of course only counts for historical times. Nowaday I'd consider everyone crazy who hates an entire people (racist).

What about "Has served in the Roman Army" if the Romans conquered some of your genuine lands and you are allied to them. I'm thinking about guys like Arminius. But maybe in 272bc that's a bit early? Can you make traits appear only after a certain date?
