I started using anti-vaxx propaganda tactics satirically.

The goal is to show how the tactic is manipulative by applying it to something obviously not dangerous.

Water is easy, start insisting that “dihydrogen monoxide” is dangerous:

Celebrity just died? “They had dihydrogen monoxide before they died, maybe it killed them”

“All traffic fatalities in the last 5 years were link to people using dihydrogen monoxide”

“Dihydrogen overdoses kill people every year”

“Why is dihydrogen monoxide in everything? Why is big dihydrogen monoxide putting this in everything, what are they trying to do?”

“I bet Trump was on dihydrogen monoxide when he thought of his tariffs plan”

Etc
