Well, there is the rub... Many things we do today come from questionable roots. Who cares? What matters is what we do now, and where our hearts are now. If my daughter sees this as a chance to dress up like Alice in Wonderland and run around the neighborhood getting a bag of candy, then so be it. Just because it's Halloween doesn't mean we're in the back yard sacrificing an animal to some pagan god.
Next I'll get slammed for letting her dress as Alice, who was obviously contrived during an especially strange acid episode. Therefor, she is obviously promoting illegal drug use.
Now, as far as dressing like a little whore, that ain't gonna happen. That's in the here and now.
Ummm, I respectfully disagree. History and roots DO matter. You can't santize it away.
