Downvotes exist for a reason and the moderation has their own thresholds for sane conversation. Most my karma has been gained by what I would bet you consider "anti-vaxxer" talking points. Best thing you can do is give a stupid person some rope, if they wind up doing something useful with it well maybe they weren't too dumb afterall.

Exactly. I remember a while back this crazy physician said stomach ulcers were caused by bacteria! What a quack. That goes against everything we know about ulcers - they are purely caused by stress and diet, bacteria can’t survive stomach acid!

His ideas just make discussions “insane” as you say.

After Marshall had proven bacteria to be the cause, science accepted his discovery and even gave him a nobel prize for it. And before his experiment, there was just not that much evidence supporting either the “stress” or “bacteria” hypothesis.

Yes, jumping to conclusions before there is evidence is stupid, but ignoring the evidence is just insane.

Prior to self-infection and treatment, he was ridiculed for even suggesting the theory.

Think "wow, your idea is so stupid I can't believe you call yourself a doctor" type criticism.

My suggestion is not "can we ban anti-vaxxers" but rather "if someone posts anti-vax comments just address them with counter arguments"

Your doctor as an actual person would likely have plenty of interesting things to say because he's not a human relay in a disinfo campaign rooted in facebook twitter and reddit.

It isn't merely a controversial topic nor an unpopular position on the topic that is problematic. It is accounts created 20 minutes ago to promote bullshit making an otherwise interesting topic a boring referendum on bullshit. How many times would YOU like to explain that covid isn't flu nor totally safe if you eat right and exercise?
