In this submission at least, it seems to be primarily low-effort comments that are downvoted. By that I mean wild assumptions, no effort to provide any evidence to back them up or just some popular saying and a dash of moralization that suggests whoever isn't sharing the opinion of the commenter is a bad person, does not want to engage in an honest conversation, has a hidden agenda and wants to drive away the good people etc.
When someone is offered a conversation and results to name-calling and straw-manning, isn't a downvote what you'd expect?
