You can't go by upvotes—plenty of comments that break the site guidelines get upvoted (https://hn.algolia.com/?dateRange=all&page=0&prefix=false&so...).
Re why I described your comment as an attack: "I don't really care what you think if you're a $foo" and "find a community of your own to post in" are hostile if not outright aggressive. Of course jrm4 is welcome here. We don't want HN to be a place where people hound other people out of the community. Please don't post like that again.
