Antifurs are actually helping the furry fandom get bigger.
By disliking and hate-commenting on every single furry video they find on YouTube, they are giving the creators views, and watchtime, and are promoting them in the algorithm, making it more likely for someone to be recommended a furry video, causing them to be like "hey these people seem cool" and becoming a furry.
Our worst enemies are in fact, our best friends. They, by hating us, actually make us more liked and well-known.
