I thought the point of Atheism was to escape the alleged intolerant nature of religion.
No. Atheism has no point. It's merely the default, catch-all, left-over position. Anyone who isn't convinced any religion's gods are real, becomes an atheist automatically, simply for a lack of any other option.
Religious people really don't understand atheism or agnosticism. It's not like we just have a coming out ceremony where we take a bible and burn it, it's just "You know, I don't know if I believe that god is real...". They make it out to be that we all gather in groups every sunday to talk about it... but we just sleep in. We don't usually even label ourselves because the label is itself irrelevant. We don't have a religion, that's it. You all believe in something, that's great, we don't. That's literally all there is to it.
