There seems to be a legitimate basis for the racism angle, intentional or not. This random article is one of many that delve into it.
I think the problem is in referencing a specific phrase, "table dancing" and not just the idea of "dancing on a table" which is more common and wouldn't be in the dictionary as a term.
If someone says anything about dancing on a table or bar, the first thing I think of is PeeWee Herman dancing to Tequila by the Champs, perhaps betraying my age a bit, followed by the music video for Hypnodance by Little Big. Other than that, it's just a random smattering of movies and TV shows (and a drunk wedding attendee or two) hopping on a table, shouting something to the effect of, "Let's party!" and then dancing very poorly.
Sure, erotic/sexual versions exist (like everything, as dictated by rule 34, of course), but that's not likely the norm that most people encounter.
It's perfectly reasonable to make a dancing joke when on a table that has nothing to do with being sexual or erotic.
I was entranced the first time I played this game on the Apple IIc. It was a beautiful game at the time and very movie-like in its presentation.
I wasn't any good at it, of course, but boy did I love watching it in action!
Scrying type spells are not in the game as far as I know. There are a lot of non-combat spells in D&D that are not present, likely because they are based on creative liberties, and difficult to replicate on a computer.
I can finally play D&D instead of always being the default GM! Yay!
It's a fantastic game and I am having a blast with it. It'd be neat if they found a way to incorporate a little more of the utility stuff (scrying etc.) but I can imagine how difficult that would be. The scope of what you can do in the game is definitely much farther than I thought they'd go!
I'm not trying to convince you, just point out it's not uncommon or unheard of. Even the article I linked ends with a statement about it possibly being just a bias and not outright racism.
Regardless, I don't think it helps either of us if we start referring to bloggers and influencers.
