Greta Christina is angry, and rightly so.
There are lots of things that make atheists angry (for all the right reasons), Greta has covered many of them.
Here’s a few more
I get angry when Christians are so condescending to atheists, especially when they say they are sorry for us. We don’t need your sympathy, were fine, life’s good, then life ends; get over it.
I get angry when religious groups spend so much time and money trying to influence government policies. (see The Brethren Express)
I get angry that religious groups get tax and other exemptions.
Feel free to send me more.
