> Good, let's try to convince anti-vaxxers, Q people, Covid-deniers and what not of that, it will surely work!

You don't seem to understand. Don't tell them on Day 1 that mask are useless, and on Day 2 that mask are mandatory under threat of jail. Tell them on Day 1 that you fucked up and destroyed mask supplies a few years before and that you're not prepared anymore. Though, that will never happen as these people want to get re-elected and do-no-wrong.

If masks are useless on Day 1, they are useless on Day 2. If not, it means that people making these statement are full of shit on potentially ANY subject and thus can not be looked upon to (including vaccination).
