I'm sure the opinions run the full gamut--they're people, after all. I suspect the tendency is toward open-mindedness though, since the Shaolin cannon itself is composed of numerous different styles.
I've spent enough time with two Shaolin monks to know how they feel. Both love martial arts in general and respect anyone with skill. One of them told me sanda was his favorite style, the other one loves them all, but especially seven star mantis. The maintenance man at the Kunming Shaolin Temples (not a monk) was an expert in Bagua. Martial Brotherhood and all that jazz.
But there are always going to be narrow-minded people who believe their way is THE way. Everywhere.
