If “accepted” means accommodated, then yes. As Pampers4U notes, there are certainly more online venues, products and events. When I started exploring ABDL more than 30 years ago, there was nothing.
Society, however, still regards us as contemptible freaks. This hasn’t changed much, and the willingness of certain ABs to make themselves objects of derision in the mainstream media hasn’t helped.
About 15 yeas ago, when the first AB retail clothing boutique opened in England, I honestly thought we’d arrived. Then came Jerry Springer and his ilk, and the reductive lens of reality television. Now, I’d argue we’ve managed to take a step or two backward instead of moving toward societal acceptance.
You can be “an optimist” all you want, but flaunting your AB lifestyle will today produce largely scorn, whereas 30 years ago, it left folks puzzled and speechless. I submit that puzzled and speechless was better.
