I for one can't wait to get discriminated against and achieve some sweet payback and try and enforce my modern day thinking a few centuries earlier.
Um, it's not enforcing modern day thinking on the old ages.
People back then didn't place strict differences on racial lines and the like. It was religious, and said line was often blurred because of various political realities, etc.
The fact that we're not allowed to marry people of other religions outright is not historically accurate. Allowing people, with a set -2 or something, is.
