Again, I suggest that you find out more about it before judging. Most Minnesota brethren who pass around information about the incident know nothing more than rumors. The reaction of the other U.S. Grand Lodges had a lot more to do with international Masonic politics than it did anything about the Grand Lodge of France being "questionable."
Also, you make a connection that somehow being a Shriner had something to do with it, yet you give no indication why you would think that. As far as I know, the Shrine has no connection to France. I'm not a Shriner, but I just don't get why you make some connection to this incident. The PGM involved is a good friend, he was badly hurt by this incident, and for people to now try to cast some unsupported aspersion on him over a decade after the fact does anger me.
Give a look at this article about the politics involved in the three competing Grand Lodges in France, with a good explanation of what happened in Minnesota:
