Nature's Laws

[Angrboda]

You are correct that atheism is just the rejection of theism and is not a world view. It never claims to be. But when you free yourself from the shackles of stupid myths you can act according to how the world really is and not as part of some "gods plan".
As an atheist with one short life, life becomes more precious.

Some atheists may feel this way, but it isn't a necessary consequence of the freedom that comes from being an atheist.

As an atheist you don't have to hate rival faith groups or people that the evil book tell you too.

No, but you can still irrationally hate groups of people for secular reasons.

As an atheist you take responsibility for your morals and nature, we aren't nice because god is watching we are just nice.

This is only true if you are a moral anti-realist, which isn't, again, a necessary consequence of atheism.

And of course we get to do what we want on sunday.

Theists get to do what they want on Sundays as well, whether that be church or something else. Plus, some atheists choose to go to a club or church on a specific day of the week. Being atheist doesn't free you from such chosen obligations.
