According to this obituary Dave died on October 12, 2021. He died from COVID. He's survived by his wife and two sons. As far as anti-vaxxers go, Dave was quite angry at the whole masks and vaccines thing. There's a positive note at the end.
David posted on his Facebook page a lot about COVID:
He wasn't afraid...
Stop being sheep! He wants a drink. So do I.
He felt there was a greater risk with the vaccine than with COVID itself (according to breaking911).
Things really heat up in August with the memes (I've noticed that August seemed to the height of the anti-vaxx meme spread):
Dr. DeSantis, M.D. proved it!
Seems we're at number 9:
Whatever happened to that Gamma variant? It looked so promising!
Wouldn't be a complete anti-vaxxer without the call to imprison Dr. Fauci.
And calling Fauci a liar...
He's had it...
Seems this is the second time he's gotten COVID. Not bad...
He's hating Facebook, but aren't we all?
He's done... (with Facebook)...
Oh, no he's actually done.
On a positive note, his friend tries to cheer him up in post-mortem:
