Unsettled by a Reddit sub?

Just wanted to vent. I randomly just came across a sub called r/TalesFromTheDogHouse which is a sub for people who hate dogs. I understand people who are concerned about dogs which are known to aggressive such as PitBulls and XL Bully but a lot of the comments on there are vehemently hateful towards all dogs, and it almost comes across as sociopathic! I wouldn't like to know any of these people in real life.
