To what are you referring - the 'tree people'? If so, I'm not sure that really follows - I mean, yes, Marston did use plenty of stereotypes in his comics, unfortunately, but these guys are supposed to have been devolved to caveman level - and yes, they're dark-skinned, but otherwise, is it really offensive to show cavemen acting as cavemen were supposed to have acted, i.e, brutal and superstitious?
