I have a reply to one of rainy's earlier posts (not yet posted btw) that addresses this precise point, but I was being just a little mischievous, subversive even, to lighten things up a little. Yes, many of these issues are indeed important, but it's all too easy to blow them out of all proportion when set against the core fundamentals that still unite us.
Imagine for one moment that we all agreed about every single detail of every aspect of our faith. What a boring, anodyne, sterile world that would be. Exactly what the NAR's would want if they are to succeed in their mission to unite us under the banner of a single w/wide religion. Frankly, I'd rather viva la difference than be drafted into their ranks.
I've just finished reading Faster Than The Speed of Light by João Magueijo, and you wouldn't believe the enmity that oftentimes tears the scientific community apart. Their 'lively' debates (especially between string theorists and loop quantum gravity advocates) are often conducted on a level that only falls just short of open warfare, and make our exchanges look quite civilized by comparison. In fact, it could even be argued that scientific progress often owes a debt to these bitter disputes.
So yeah, we have nothing to be ashamed of. We're only human after all, so we're almost bound to disagree over some things. But sometimes we need to take a break from the heavy stuff, sit back, & try to put things back in some perspective. We can get too wrapped up in our own little worlds, and forget there's a bigger world out there.
