Ubiquitin, I wasn’t trying to imply that you have actually mocked anyone.
I think it’s reasonable to assume that someone on an anti-shul campaign has a malicious agenda. I don’t think that about all/most anti-vaxxers, I think they’re being swayed by anecdotal evidence and emotion.
It is a mitzvah to mock people whose agenda is anti-Torah. I don’t think it’s a mitzvah to mock anti-vaxxers.
