I got blocked by him on Twitter (in 2012!) for mocking his whackjob antivax views. He was espousing shit headed antivax nonsense long before it was fashionable.
Antivax goes back at least a decade before your 2012 blocking. My kid was born in 2001 and the whole vaccines cause autism thing was already big. In fact, I'd suggest it was nearly mainstream at the time.
When the study that suggested the correlation with autism got thoroughly debunked, nay, proven willfully fraudulent, it fizzled out a little bit, but has still stuck around like a raging case of herpes to this day.
Yes I know. I've was there for it too mocking these dinguses. But it only became mainstream with COVID when it sort of metastasized and merged with a bunch of other deranged conspiracy nonsense via MAGA & QAnon.
I certainly am. I also got blocked by Kirsty Alley, Rudy Giuliani and Michael Avenatti for criticizing their cult, grift & grift respectively. I'm sure there are a few others I don't know about.
