Can't say the language bothers me; dialect is a writer's tool and I don't associate poor english with poor intelligence at all, in any way. But then, I'm from the South and I talk all funny too.
But when you add that to Thunderball's generic dialogue, and the generic evil horny arab, and the stuff about Venus saving the savage Wakandans...it does get a bit odd. On the whole I think you're making a good case.
This raises another question: parker's obviously an intelligent guy. Let's say he reads this and says, wow, some of the shit I've been doing is fucked up. What should he do about it?
