I appreciate the enthusiasm and the support, but what I got out of it was two extended paragraphs of simple questions I think everyone at least can be certain of the answer.
We obviously have no idea whether or not it was David Moo's idea to use the accent, or if it was the directional choice. We're never going to find that out unless somebody from 4Kids speaks up about it. I'm just confused why you're asking a FUNimation voice actor for that answer. A lot of the talent in Texas hadn't even seen the dub, or One Piece in general until it was acquired by FUNimation.
The second question is more fair, assuming he has seen the 4Kids dub. The other half of it is something he can relate to more, but then again we always know how some sub vs. dub arguments turn out.
