According to this story Josh died of COVID. He wasn't vaccinated. Wasn't against vaccines generally but got suckered by the "politicization", according to his wife.
Let's let Christina, his wife, tell us why Josh didn't get vaccinated. From the story linked above:
She said that they didn’t “know hardly anybody that had gotten real sick and figured we would be OK.” In the spring, Josh himself shared an article critical of Dr. Anthony Fauci, writing, “this is why I don’t believe 99.9% of what’s said about this virus.”
Now, eligible family members are getting their coronavirus shots.
“It’s just a fight out there. This side and that side, and political garbage...You don’t know who to believe,” she said. Christina Tidmore said she has no doubt that they would have made a different choice now, knowing so many more people who have contracted the virus.
RIP Josh.
