Still waiting for you to provide me with some documented facts that back up your claims that some Mohawks want to bring back ceremonial cannibalism... tap... tap... tap...
That wasn't worth responding to since it's "known". In fact, to get the Lawgiver's name spelled correctly I went to a site that started it's commentary concerning his and Hiawatha's efforts to eliminate "cannibalism", if not "ceremonial cannibalism".
Now that you've pinned things down a bit better, I'd advise you to simply go to every First Nation's internet discussion site and look through their archives concerning the topic.
Since there are hundreds of such sites, and a gazillion Iriquois of every nation making posts, it might take you a while, but I have no doubt at all that you will be amply rewarded.
Somewhere in my vast warehouse of "interesting things from the net" I have the URL for some of the posts I've run across concerning the matter of bringing back this particular custom. Someday I'll search for it for you.
In the meantime rest easy that no one's going to be doing this anytime soon since it first requires eliminating the "blood quantum" under Canadian law so that folks can sort out who wants to be a Mohawk, or something else.
