Regardless of whether the video was a joke or not, I think that alot of christians try to blend christianity with all kinds of stuff just to get people interested, which I don't think is the greatest idea.
Flexibility is great, but if you're trying to get people to believe in jesus, then you should get them interested in jesus.
I think most of us could be more open minded, but I also think there is a point where you do have to draw the line, and I think that the video, whether made with good intentions or not sorta makes light of serious things.
