Yes, the Voluntary Human Extinction Movement, VHEMT, is still around, though not as active as they once were. Les Knight, the creator, has all but aged out of his group, which he started in Portland in 1991. As far as the AN community, VHEMT is almost irrelevant these days, especially when compared to the newer and more public interfacing non profit Stop Having Kids, also located in Portland (because of course).
Les is old guard. Unlike the younger generation, he is very nonconfrontational and never proselytized or pushed his beliefs on others. He has always stayed in his lane, and he never seemed interested in engaging with or commenting on the larger online community outside of his group - he did his best to stay out of the drama. I know he wasn't fond of Gary (Inmendham), but he still allows Amanda (Oldphan) to promote her shit in his group, and I believe they are still friends.
Les was one of the very first people talking about AN publicly, over a decade before the word "antinatalism" became the term. He has done his share of media interviews over the years, including Tucker Carlson back in '05 and the New York Times did an article on him in November 2022.
I personally lost respect for him when he refused to address or criticize immoral and problematic behavior going on within his own group as well as the larger community, though he has made some efforts to distance his group from promortalism. He is passionate about his beliefs, but not about moderating and managing the people within his group, which to be fair, are two very different skill sets. He understandably got burned out after so many years and dialed back his online activity significantly in the late 2010s.
