Ok, there is a reason he is saying that. Furries are an anthropomorphic species, correct? Most likely the way to get a furry is for an animal and a human to have a child together, which makes many people feel uncomfortable because animals (dogs, cats, etc.) are meant to breed with other organisms of the same species, not humans. This raises many questions that people cannot answer. Plus, the ways that dogs/cats/whatever breed is much different then the way humans breed. It is not physically possible for a real anthropomorphic species to exist, therefore making some people (again) uncomfortable. Plus, some people dress up as animal like creatures, which can be frightening to some people. They behave in unique ways and, to quote naz, “fear what they don't understand”. This makes them anti-furry because they do not understand the way furries minds work. And some people just dislike the idea of furry (eg. TheCornhuskerDude) and openly say that they don’t like it.
