Great question! I think it goes both ways:
"Christian" as in "we should be nice to all of God's childern"
and
"Christian" as in the religion that not so long ago in human history said the same thing: Believe what we believe or we will punish you for it.
I am not pinning this to religion specifically, just using it as an example for how groups of humans act.
I find it interesting that I am interpreting the information that Hobbit posted on MC Clubs is that one of the likely inherent tennants of these types of clubs is they should be a "threat" to other clubs.
Perhaps I don't understand what a "Christian Motorcycle Club". Maybe a Christian Motorcyle Club is the same thing as a 1% club only they have church functions as well or they are all the same faith.
No matter what though, this is some good information.
I think there is a Christian group with a 99% patch. I like the thinking behind this but, excluding the Muslims, Jews, Atheists, etc… may knock a Christian patch down to say 38%
