No. Most religions have a strong social-bonding aspect. Joining a club that strengthens your social-connections is prudent.

I'm just trying to figure out why they claim so fervently that "objective-morality" is vastly superior to "situational-ethics" and yet, can't provide a LIST of practical, universal, real-world, modern day "objective moral principles".

I mean, if you (and many others) claim that "love" (agape) is the top moral principle, wouldn't all christians be very strongly ANTI-WAR? If your primary "objective-moral-principle" is "love", wouldn't you be very strongly ANTI-DEATH-PENALTY? Wouldn't you be very strongly in favor of HUMANE TREATMENT OF IMMIGRANTS AND PRISONERS AND THE HOMELESS?
