Atheism is not a crutch, in fact atheism doesn't even exist.
Is there a word to describe people who don't believe that Thor makes thunder? A word for people who believe that there are no shadowpeople? A word for people who don't believe that soviets drilled a hole into hell? A word for people who don't believe in horoscopes? A word for people who don't believe that Milton Bradley cracked the master secrets of the universe via a ouija board and they in turn sell that secret for $19 at walmart?
No, those are just people. (smart people... Do try to keep up here!)
To classify everyone who doesn't believe in your invisible magic man in the sky together under your 'atheist' label makes it easier on your enfeebled minds but it doesn't make it accurate.
Now if you want to talk about a crutch we can talk about religion, however this thread is about evolution not the verbal diarrhea that you insist on vomiting forth about your invisible friends.
Most progressive churches realizing the overwhelming scientific proof of evolution have changed their beliefs to reflect that god created everything by evolution... This is how well evolution truly is. Many christian denominations have taken up the cry to self protect. Not you however, next you'll say that the earth was created in seven days, start speaking giberish and lobing snakes at people... Thats usually the next step for you cretin-ist isn't' it?
