What is wrong with some of the people here?

Sorry for the rant but I was just looking at a post by a proud dad showing off a model his son made. Many of the comments applauding the model, giving positive feedback, have negative votes, meaning multiple people downvoted them. This isn’t the only post I’ve seen this happen.

Most of the people here are great and supportive, but it also seems to have a higher ratio of negative members than other subs.
