As someone who who regularly comments on 'negativity' on the forum, do you not think that you are simply adding to it by disagreeing with other peoples opinions? Everyone has different opinions to others. Every post would be full of disagrees if everyone took the attitude of disagreeing with anything they disagreed with. A like and a disagree are not opposites of equal weight. A like is a friendly agreement, but a disagree seen as far from friendly and/or incredibly negative by many.
Are we not all on the same journey here? Rather than kicking someone who is having a problem when they are down, or (not aimed at you), trolling, is it not just best to say nothing at all? Or even better, offer a bit of support even if you do not agree with the position that they are in from your perspective.

@Durzel, imho a disagree should be accompanied with a statement as to why, otherwise its simply a difference of opinion that is simply a part of everyday life. At least when accompanied with follow on comment, or simply, just a comment, then there is some context to the difference of opinions.
When I was a moderator, there was a discussion about disagrees. Quite a few posters use it to weaponize arguments. Unfortunately my/Durzels 'accompany with a statement' was not taken on, but at least the disagree button no longer counts towards the posters score so you are no longer penalised for someone openly having a different opinion to you. As for weaponizing disagrees, gratuitous use of the disagree can lead to a warning and/or temporary ban, as some that partake within these forum walls will already have found out. By following up why you disagree, it shifts the burden of proof away from why you might disagree, especially when there are multiple disagrees by the same person on the same topic.
