Not all religious people and not all religions were responsible for prop. 8.
I would agree but go back and ready J Bryson and Mestemia's posts above.
Likewise, there are plenty of atheists who are against gay marriage, as well. It is not just a religious thing.
I would immediately question your sources. That is not to say there can't be an atheist against gay marriage... I have never met one. But it is a religious thing. I have quoted the bible to you above. An atheist doesn't believe in a god. That's it. A christian believes in the bible and the bible says homosexuality is so bad and so wrong that you are to kill and murder them and you will not be held responsible by god. Their blood is on their hands. Thats the christian bible.
It isn't really fair to dump all problems and all complaints against theists. Atheists aren't any more perfect than theists are, in general.
No one is dumping all problems. This is one problem. And its not all theists. Some theists dont have a problem with homosexuality. But there is no atheist union or organization that preaches homosexuality is wrong. There is however a bible condoning hatred and inviting murder for people who are gay. What I take away from the bible as an atheist and that gay people were here during biblical times and prevalent enough that they had to include them in the bible. When are people going to realize that some people are gay and some people have brown eyes and big noses. They are not going to go away, nor should they.
And no one is implying atheists are more perfect. The stated argument and posts never implies that.
