Religion bashing

I've found recently that I have a strong affinity for bashing religion. I'm not sure where the innate pleasure of trying to tell people that everything they believe is a momentous tower of lies and over embellished fables comes from. Nonetheless, it exists. The inner turmoil is, if you take away someone's faith, what do you replace it with? In general, churches are great for bringing people together, instilling good values, creating excellent charities, and building great communities. How can people replace all of that in their lives once you disprove their beliefs? The debater in me wants to win the arguments, but the compassionate person in me wants to let them have that crutch. Aaaaagh!
