I think you don’t really grasp the concept of a hivemind, where users of a platform tend to have collective set of views deemed acceptable and unacceptable by the community. It doesn’t necessarily make them wrong, it just means that it is a view or opinion that runs contrary to that of the community. Reddit was a shit show for that (and I know you came from there due to your use of karma), and Lemmy has it too. The entire purpose of the up vote/downvote system is to increase/decrease comment ranking based on users perception of comment quality, though people tend to use it to show disapproval (as you did with my previous comment). There is no "normal’ when it comes to this, as it is entirely dependent on the instance and subcommunity’s collective views.

Furthermore, let me introduce you to the actual definition of gaslighting, per Merriam Webster:

1 : psychological manipulation of a person usually over an extended period of time that causes the victim to question the validity of their own thoughts, perception of reality, or memories and typically leads to confusion, loss of confidence and self-esteem, uncertainty of one’s emotional or mental stability, and a dependency on the perpetrator
2 : the act or practice of grossly misleading someone especially for one’s own advantage

Now, in what way did I gaslight you?
