I wonder if a modern day american with a gun would also be considered a stereotype...

Americans are commonly stereotyped as gun loving, but I guess stereotypes don't allways translate into characters.

Perhaps things are racist or not depending on how reasonably accurate it is? Having a roman character running around everywhere in a toga would likely be considered racist but if they go into battle with a Gladius then that could be considered reasonable. But someone of a different race (doing this in real life) realistically and respectfully portraying a black person would still likely be considered racists.
