One would expect a university provost to get his facts straight. What the Wiccans say is this: "An ye harm none, do what ye will", which is often stated as "Do what thou wilt, and ye harm none". This, of course is very different from Crowley's worldview, where the individual is free to do whatever he wants without any concern for the well-being of others. By quoting only the first half of the witches' credo he gives the appearance that they are in agreement with Crowley, but if he actually left his comfort zone once in a while he might see that there is a huge gulf between the two.
This is typical of those who attack Wiccans.
Believe it or not, it is possible to be Conservative AND Wiccan (particularly in the Britain, where it's much more formalised)
