please tell us what the words "endowed by their creator" mean and where those words are found?
Men who were willing to shed their own blood for their freedom wrote those words.
Just because SOME of them believed in imaginary sky fairies does not take away from their sacrifice and courage.
Just once, THINK.
A belief in a higher power was the common belief of the founders and remains the belief of a vast majority of the people of the entire world.
You are free to be an athiest if you choose, but attempting to denigrate the majority will get you nothing.
Rights endowed by the creator sometimes have to be secured by men when other men attempt to take them away.
Using terms like "sky fairies" just confirms that you are an ignorant, intolerant, scum sucking asshole. i.e. a typical liberal.
