So, it is Openly Secular Day, and I wanted to participate! I am an atheist. I'm also a vegetarian and a brunette who likes dolls, poetry, silly stuffed animals, and cats. The point of Openly Secular Day is to share the fact that you have a secular identity, because often people don't realize that they already know or are friends with an atheist (or humanist, agnostic, etc). So now you know one: me! You might know two if you know my husband Anblar. He is agnostic.
My basic reasons for being an atheist are pretty well summarized by Stephen Fry here. I do think atheists have a great responsibility for social justice in the world. I believe that when you die, that's it, you're dead. As such, it's really important to try to work to improve our world as much as possible for the people in it!
Anyway, that's it. :) If you have any questions about atheism in general or my beliefs in particular, please feel free to ask. I also activated the anonymous option on my Tumblr ask box if you'd prefer that.
