I should probably admit a bit of bitterness here...(I dated a girl who was religious.. I thought it could work, me not being religious, her BEING religious (it worked for my parents!).. I was wrong.. OH so wrong.. She dumped me, claiming "I can't believe someone seemingly so intelligent could even question the existence of God".)
For the most part, if people don't try to force their beliefs on me, then i won't criticize them and will be a-ok with letting them believe whatever they darn well please.
However, when people start to try to question my intelligence, attack me personally, and show up at my door and at my work forcing their beliefs on me when i have zero interest...
I hate that. I also find blind devotion to be a weakness.
I took a class in University titled "The Existence of God": The course description suggested it was a forum to debate for and against the existence of God.
The class turned out being taught by a noted Theologian who started off the course with "There is no debate. There IS a God. Here are the reasons why...."
When you get down to the fundamental argument.. It all comes down to the believers being unable to accept that we may NOT have an ultimate purpose. We are just here. Another bacteria in the cosmos. We are born, reproduce, and then disappear.
The argument FOR God is that we HAVE to have a purpose.. Why would we exist, otherwise?
I don't get why they can't just accept that we have no real point, and should just enjoy our lives.
