You're right on the money about how loopy some Catholic women's religious orders have become. On a more positive note, the loopy ones are moribund. Another two decades and they will be consigned to history. And the last generation of these nuns will have made a mockery of all the hard work, faith, love and dedication of their predecessors. What a legacy of junk!
I went to a high school run by Dominican nuns and the fact that Dominicans were involved with this incident doesn't surprise me at all. Ours never went so far as to promote paganism, but they were pretty leftist and unorthodox.
