First, I think the joke about Cracker Barrel is pretty funny and it distresses me to no end regarding the reaction to it. I mean, the name has “cracker” in it, right?
I don’t mind that Twitter removed replies that were dramatically hostile though I start to get nervous about what blocking accounts does to public discourse.
Do we want to live in a society where corporations get to decide what we can say online? I am concerned that the more we go down that route, the worse things will get. After all, a well educated, white, rich person can say oppressive things in a way that sound reasonable while a poor person without the same education will be on the business end of such policies.
A final point I would like to make is that the US is by no means culturally unified and I would hope that black folk and everyone else is quite safe travelling at least through the rural West. So I would hope that the same concern about prejudice would apply between parts of the US geographically just as it does between racial groups.
