A problem I would see with such extreme role play is inevitably someone would say something racist, xenophobic or intolerant, and someone else would take it seriously and report the person.. The person would claim'I was just role playing' and open up a pandora's box of problems. Most people have had experiences with someone making a hurtful nasty comment then claiming they were just joking. Similar issue here. Where do you draw the line? 'I was just role playing' would be seen by some people as a license to be as hateful, nasty etc as they want, and not have any consequences for it. Say, someone decides they don't like me personally, so they decide they will 'rp someone who is racist against Viera' and use that as a way to verbally attack.
