A further thought.
To me, the fundamental question is; Is it better for the hobby to have more people playing?
Again, totally just speaking for myself, the answer is an unqualified yes. It makes the hobby more socially acceptable, it ensures that we still have a hobby in the future, it makes it easier to find players and DM's. It means that there's more money for creatives to bring out more goodies for me to enjoy. So, yeah, it is better for the hobby to have more people playing.
Which, alternatively, means that anything that results in less people playing is bad. Adding nudity to gaming art has not increased the number of gamers over the years - no one says, "Hey, yeah, I totally got into AD&D for that succubus picture." OTOH, removing cheesecake art from the game has coincided with huge growths in the hobby. Additionally, other companies, like Paizo, had moved down this road, pathfinding a route so to speak, even before WotC did it, so, there is a considerable precedence here.
So, in what way does the game or the hobby benefit from using this type of art?
Oh, and on a total side note - I too am a cis white dude creeping up very close to 50. Sigh. So, yeah, take from that what you will. And, I've got a stack of Heavy Metal magazines to prove that I'm hardly a prude when it comes to art. But, again, time and place. I love artists like Luis Royo. Fantastic stuff. Frazetta, Vajello, Julie Bell. All fantastic stuff. Love it to pieces. However, I don't think that they really have a place in D&D material. Or, at least, not without some set up first.
