If someone identifies as a rat and I am required to agree with the fact that they are indeed a rat, may I poison them or set a trap for them or just stomp their brains out?
I don’t identify with doing a “furry” any real harm for dressing the way they do but a little ridicule could be called for. After all, they brought it on themselves. If dressing this way disrupts a classroom to any extent, then discipline would be called for.
