Opposition to _coerced COVID vaccination_, whether through law or through imposed burdens on those that don't, isn't antivax. Not even close. Speaking of lies, children are at virtually zero risk of death. Even if we put aside concerns about the COVID vaccine, there is no legitimate reason to require vaccination of the young. Being able to post videos that offer different points of view, many of them by healthcare professionals and people in medicine, is a good thing. The frantic desire to silence all discussion, no matter how level-headed and banal, that departs in the slightest from the "official narrative" only creates suspicion and distrust. We're not talking about censoring calls to violence (some of which were have not been censored by media platforms, btw, because the targets are political opponents). We're not even talking about weird conspiracy theories that barely anyone but a few people believe. We're talking about discussion about an experimental vaccine and the real dangers of COVID backed by data.
(And btw, the whole antivax "controversy" is a media circus. 98% of Americans have the full regime of vaccines. That's a lot of vaccines. There is no real antivax problem. It's media hype. This given even the moral objections to e.g. the rubella vaccine's origins.)
