I can certain be empathetic with the reddit jannies wanting reddit to do something about the anitvax stuff, but reddit won't spite its financial interests nor should it. The more effective protest is to find an alternative to reddit. Deny them your time and money.
If they had a scientific basis to do so, you could maybe consider it justifiable (though I wouldn't personally).
For example, if it was people saying that washing yourself in cow dung would cure coronavirus (something which happened in India), okay, fair enough. Id rather let people talk about the things they want to, make their own choices, and present them with information which is correct to allow them to make an informed choice.
Thats the bedrock of liberal culture. You present people with information, and allow them to make their own choice on the matter.
What's happening with covid is that there was very little information to begin with, most governments published contradictory information, and, in a bid that resembles ivory tower elites thinking "the average person can't handle the truth!", information or discussion is being suppressed.
Talk to your doctor about hydroxychloroquinine. Go into whatever other medical treatments that you want to go into, as long as you are informed of all the information, thats all that should matter, right?
But, apparently not. You can't bring up the possible benefits of Ivermectin, only the cons. You can't bring up the cons of certain prevention plans, only the negatives.
Sucks I guess
