I'm starting to understand why
@Snarf Zagyg frequently posts his threads and then walks away and doesn't engage anymore.
To reply more substantive to the OP.
I think that the issue with discussing inclusivity, especially as compared to the past, is two-fold.
First, when you bring up examples like the one in the OP (or countless others), people who liked and played those games back then get defensive. Instead of thinking about the issue, they feel like you are "yucking their yum." But you're not! Things were different back then. I mean, if you look at almost any popular culture from the '70s or '80s, it will contain elements that both reflect the times and can seem ... questionable ... at times. That doesn't mean that people were bad or evil back then, just that the cultural mores were different, and that we should be aware of that and that we can do better now!
Second, a lot of people are blind to the issues. When I was growing up, it was common to bike everywhere. I remember it as a time of unfettered freedom. Think of it like Stranger Things (maybe a little earlier time, but same gist). Day or night, I could be on a bike, out somewhere. Anywhere. Sometimes in packs of kids, sometimes alone. It was awesome. It is one of my most treasured childhood memories.
So I was talking to a friend of mine. She grew up in the same place. Same time. And we were discussing biking. And she agreed it was great, but she said that she never, ever, biked alone at night, and wouldn't even bike alone in remote areas. And I was kind of stunned- because, you know, it was safe, right? But she explained that there were older men in some areas that would catcall and harass girls. Middle school girls. And she just felt that lack of safety. Thing is- I never knew that. I had no idea. I just assumed everything was the exact same, because ... why wouldn't it be? But from a young age, her experience was already very different than mine (in a lot of ways, I know, but I'm just pointing this one out).
In other words, people can be blind to certain things because their experience is not universal.
Anyway, to sum up- D&D is awesome. Everyone should be welcome to play. No one should feel uncomfortable.
