Hard disagree. Down votes shouldn't be disabled, and I'm disappointed that Beehaw has chosen to do this.
What about comments that give dangerous advice to an unknowing audience?
That's one good reason for down votes. People may upvote it not knowing any better, and when someone comes along to correct them, the damage is done. Other knowledgeable people can't downvote it to make sure that dangerous advice gets pushed to the bottom, they just have to hope those that upvoted come back, see the rest of the discussion, and remove their upvote.
Right? Fucking tankies crying tears into an ocean here.
