Not fully sure what you mean here. I did not downvote your comment. I also have no idea what "seems like an incredibly disingenuous statement". I posted how your comment comes off to me, in case you were not aware it was coming off that way, or in case I was misinterpreting then perhaps you would clarify.
I'm not sure what you want me to clarify? At no point did I indicate that it's okay to downvote people you disagree with. They should constructively contribute to the conversation, and in cases where they are not, the downvote button should be used.
