I cannot defend BioWare regarding SJW stuff anymore. That's it.

That is correct, however, a lot of Noble families were not just magically Noble out of thin air. Nobles had genealogies that would go down the family line to "prove" who they are related to, and why those special people were important. Noble families often started from a nobody being thrust into a remarkable situation and somehow accomplishing something considered impossible for their Station. Even the war bands mentioned here, were not just born Noble, they made themselves Noble by doing something significant. Knighting is a real system, that is in fact still used today, admittedly for far less heroic things. For example Patrick Stewart is now a Noble, but was not born as one. Does Hollywood play up the Knighting thing too much? of course, it plays up everything too much. But the fact remains, I will not allow an argument about Kingdom Come being "historically inaccurate because the character is a peasant" to go unchallenged, because that's ridiculous. I mean for goodness sake, Liu Bang, the Founder of the Han Dynasty and Emperor of China, was born a Peasant. 

Edit: I hope with that cleared up, the people who made these inaccurate assertions about Kingdom Come will realize their mistake, and not insinuate anyone who defends Kingdom Come or historical accuracy in games to be unpleasant people, and will rethink their knee-jerk assumptions in the future. Have a lovely day.
