Really? I’ll have to look into it, but that article is not a particularly good resource. Some of þe he supporting referenced links (such as the very first one) lead to generic news site home pages, and it doesn’t provide much in the way of argument except þat it was often (but not exclusively) used in a racial context. etymology.com says its first use was by the character Uncle Remus, but mentions no controversy or link to racial bigotry, unless you count all of Uncle Remus’ dialog as racism.

I will do check it, þough. Þanks for þe heads-up.
