Great show Bob! Don't agree with your opinion on double standards though. I personally, don't want them around. Yes, I know there are double standards, I just don't think we should accept them.
Now i know that not everyone will agree on this, but here's my opinion on the whole race in movies thing. I only disagree with changing a persons race in a story, if race actually factors into the story.
For instance: Last Airbender. I did mind that Katara and Sokka were white, because inuit culture was a factor in their character creation, and everyone else in their tribe was inuit. I guess you could argue that they're grandmother was from the Northern Water tribe, where there were mixed races, but that fact was glossed over so fast, I don't know if anyone remembers that part. And it really WOULD seem racist to say that the prosperous tribe is the one full of white people. Ya.
But I did not mind that Aang was white, because you don't have to be from an eastern culture to actually become a monk and the monks in the movie did have different skin types anyway. And, he looked like Aang. Technically, Chinese, Arabic and Inuit don't actually exist in the Avatar world, they were just inspirations for it.
The Fire nation i didn't mind, because i also had a bit of mixed races, and you still had those eastern influences (though casting the VILLAINS as arabic my not have been a smart move with everything going on in today's world)
And even then, i might (keep in mind that that is a very, very slim "might") have still been okay with it if the actors were actually GOOD.
Also: Goku is an alien, Nick Fury is black in the Ultimate Comics and therefore has a different backstory, Michael Clarke Duncan was great as Kingpin and his backstory never came into play (so i don't know if his nationality was a factor in his backstory), and to flip to a different subject: I don't agree with Angela Bassett playing Amanda Waller because her size is actually a character trait and she's the only other character in the DC universe besides Candy who doesn't look like a super model.
And to end what now looks like a rant: We need to stop with the white guilt. Please. Because it won't make things better. One of the arguments going on in Canada is that the First Nations continually ask for more and more, guilting everyone else into giving it to them-- to the point that some have become lazy and greedy (and before you call me racist for that, i learned about this from someone who is First Nations)
(Hopefully, all of that made sense. I'm not the best at conveying my thoughts. And please don't hate me if i got some nationalities wrong)
