I guess there is a difference between accepting discussions around a subject with people you disagree with, and accepting someone creating an account specifically designed and named with only one goal : bad faith and low effort posts (yes this is what such a username clearly seems to announce to me).
I spend much time having great discussions with people both online and afk about vaccines, people who are both pro or anti, and it is sincerely interesting. But seeing such a username is as stupid as seeing someone named "vaccineguaranteeyoursurvival". Those username are themselves clearly false statement that are meant to create unusefull discussions.
Hope this ban isn't getting canceled.
I agree : the question, if it is one seeking an actual answer, is a bad one. But I guess we can be more charitable and view this question purely as a conversation starter around an issue. Maybe OP wants to have the view of a wide number of people around this subject one general, and purposefully makes questions as imprecise as possible. If I am not mistaken, I saw other questions of the same type by OP before.
