I would agree with this. I believe in the Founders Era there would not have been the desention between Muggles and wizards. I think the Burning Times and resulting Statute of Secrecy is what caused the rift and therefore the feeling that Muggles were less than wizards. I think for the most part, wizards and Muggles lived together quite well until fear and bigotry took over the Muggle world and caused the Burning Times.

If your thinking of founders era i don't think that distinctions would be so defined. Us And Them labels tend to have roots in conflict or traumatic separations like the introduction of the statute of secrecy maybe.
