I would be embarrassed but I wouldn't leave them. That's just crazy. As long as they didn't act like a furry around me, the rest of my family, and my friends I wouldn't care. Everyone has their weird fetishes or hobbies. Though I think the idea of being a furry is just strange and I wouldn't want to be near one, I don't really care. Putting yourself in a costume seems more normal than being otherkin.
