Man, please, learn to read. My whole point is that you should not care about what people upvote.
So once again: if you are okay with the original comment/post - which means you are fine with keeping Nazis on and what they have to say on your platform - then you should be okay with people who "react" on that content.
Or maybe you aren't fine with it, so you should delete the offending post or comment, and then you won't be bothered by the reactions either.
