Atheism is a form of religion...

[Aoi Magi]

I agree with everything you said, but here's the kicker: theists don't. When they regurgitate "arguments" like this, they don't realize that either they're saying all religion is invalid/evil/wrong, or they've said nothing of value (akin to telling someone right next to you that there's a slight breeze - a fact they've undoubtedly noticed and knew about before you finished your sentence).

You need to understand that while talking to theists you CANNOT talk in the same tone which another adult is supposed to understand, remember they consider themselves to be ignorant children following their sky daddy, so to make any sense to them, explain things as you'd explain it to a toddler.
