That is a mischaracterization. It shows the hypocrisy of people disparaging an incredible vaccine, and paying the ultimate price. No-one is celebrating deaths, but they are exposing deep idiocy.

I fail to see any hypocrisy. Wouldn't it only be hypocrisy if you refused the vaccine yourself while encouraging others to get it, or vice versa? Also, there's definitely celebrating death going on in that subreddit.

You're right, that's a mischaracterization. These people aren't hypocrites, they lived and died with their core tenets of mask-aversion intact.
