Technically speaking, a furry is an enthusiast of anthropomorphic animals, or animals with human traits. Examples of anthropomorphic animals are garfield, Pokémon, piglins from minecraft, and the snakes from ninjago. If you were a particular fan of animals that had human traits (including human speech) you’d technically qualify as a furry.
“BuT fUrRiEs ArE aTtRaCtEd To AnImAlS!”
No, those are just people into bestiality. Zoophiles and furries might have a slight overlap, but they are not one and the same.
TL;DR: To bully all furries would be to bully more ppl than you think.
