What is the Real Purpose of an Atheist Forum?

So what kind of things are happening at these atheist organizations? I come from a culture where philosophy and morality is separate from the religion. There's no temple to go worship a god or anything like that. We only have Shamans, if you believe in that then you would go seek him for spiritual healing. Like the way a person would go to the doctor if they felt sick. But for those who don't believe in Shaman powers, we just go on for years without doing any of that stuff. In other words, we just live our every day life: work, play, eat, sleep, etc. It's not necessary for a person to observe our religion so nobody gets ostracized when they don't. I guess that's why I don't understand why atheists are compelled to get together. Couldn't they just live their everyday lives and forget about those who are religious?
