I guess I'm an Atheist, but I really don't like the label/name, just sounds douchey. I think when you die, you just rot in the ground forever. A God who, obviously knowing no other option, decides to have his son tortured to death for "your sins". I may have been a bit naive as a teenager, but, even if this were true, this just screams "I'm obviously the best thing to ever happen to you", keep trolling for attention.
Also, he's fucking god, can't he just do whatever he wants without having to kill people, let alone his own son? That being sad, there being no god, I'm not dismissing bad things, you still shouldn't kill/rob/rape people, but that's more of a common sense thing.
If anything, it motivates me to even accomplish more with my life in the small 75 or so years I have alive. I think a lot of Atheists go the whole "life is meaningless, so fuck it" type route, which I admit attracts a lot of people, especially people just looking for that particular excuse. No, your life is still important, meaningful, and a winnable fight even if there is no after life, which makes even more people(probably) waste their life as well "if I don't drink/do drugs/ devote 18 hours a day to worship, God will accept me" meanwhile they're wasting their life just like the people who say fuck it. I'll write more later, but these are the main things why I am the way I am.
