Sometimes it's just nice to hear unrestrained rants against religion. One of my favorite sources is Pat Condell's series of videos on YouTube. Here's a sample:
I love this guy, and I see nothing disrespectful in being truthful. The fact remains that most religions are simply interpretations of antiquated stories that don't tell us anything useful beyond providing a window on the culture that wrote them. No one should feel hesitant about pointing that fact out.
Anyway, Condell has a whole bunch of videos on YouTube, and I encourage you to check them out.
