are you asking or telling us?
Well, if it helps, when I joked about Ronnie having a bale of cotton on each shoulder and shouting "Light weight, baby!", the humor (as I saw it, needless to say) was the idea of Ronnie - in those historical circumstances - being too dumb to realize that there was no pride to be taken in being the most productive slave.
It wasn't meant to be pro-slavery (as I've mentioned: I'm Jewish, so my people have been slaves too) or anti-black.
It was just a "dumb Ronnie" joke - albeit a willfully tasteless one.
