If people are downvoting and not commenting there is probably an obvious reason why.
Usually you just said some type of heresy in that community, like going to a NASA forum and saying it’s idiotic to still be trying for manned space missions to the moon or elsewhere.
It’s so anathema to the community they don’t even want to engage in a discussion about it, they just want to say “you’re wrong/I don’t like this” and move on.
Far more civil than how religions used to deal with heretics, imo
