I'm super late to this party, but I wanted to add my two cents:
-I have worn lolita into the park before with no problem. Granted this was also at Christmas Town, but my friends and I were completely decked out in wigs, petticoats, etc.
-I know this woman, we have mutual friends on facebook and I have seen her at our local cons. That entire crowd are the types to make a big deal out of nothing. My friend also speculates that she was trying to come into the park practically wearing half a fursuit, which is much more obtrusive than simple ears and a tail. I know people who wear these things and the tails are so big that they drag on the ground. She could be completely innocent, but if her behavior was anything like the local furry/rave scene tends to produce at cons, I can fully understand why Busch didn't want her in the park dressed like that. It could also have been a newer employee to have said something at first, and the whole thing escalated from there.
I don't know, I just have a hard time empathizing with people like this. Furries are nothing really new to me, a lot of them can be kind of cool and have a minimal sense of self-awareness. This person in particular does not. (PS. was there really a 4chan thread about this? That's rich.)
