You make some good points.Some people on here keep linking Atheism on here with a belief in Darwinism or the big bang theory when atheism can exist without the need to believe in either theory.
I'm an atheist and I don't believe in creationism,Darwinism the big bang theory or any religion or religious book.
I believe we will never know if any of the above theories are true and all have been used to defend the bigotry of various people.
The bible as been used to promote child abuse and racism by various people. There have been scandals from just about every religion of the leaders of those faiths committing crimes against children and it being covered up. Religion as been used by some to defend wars such as the crusades.
So what does that say about religion?
If you have any sense you will realise it does not say anything about religion. It speaks only of the twisted mind of the individual who uses religion but would also use anything available to defend them perpetrating their twisted desires and forcing them on others.
In the same way it is wrong to believe that all atheists use these examples as a way of attacking religion or that all atheists have the need to attack religion or force their ideas of their being no god onto others. By the same token not all people of a faith have the desire to convert others to their faith.
I believe that we can debate things and put our opinions across and the problems arise when we personally attack others for their views or try to brain wash others to our way of thinking.
Bigotry is when we try to assign values to a group of people because no group of people no matter how small will ever have all the same values.
It is not religion or atheism at fault but the individual using them to promote their own prejudices.
Just remember a good scientist does not "believe in" anything. He expresses a degree of confidence based on the evidence.
