If you do something I think is good, I will be glad. If you tell me that your religion was the reason for your action, I will not be any gladder. If you do something I think is bad, I will be saddened and may decide that it is my duty to oppose you. If you tell me that your religion was the reason for your action I will in no way revise my opinion of your action.
Any religion that wishes to take credit for the good things done in its name must also take responsibility for the bad things done in its name. The hypothesis that the world would be worse without religion is as untestable as the hypothesis that it would be better.
The natural world contains no evidence for the existence of the supernatural. I have chosen not to believe in things for which there is no evidence. I will steadfastly refuse to acknowledge any reasoning based on the existence of a supernatural being as valid. If it is impossible for you to engage in discussion without invoking some supernatural entity then it is impossible for us to have any meaningful discourse.
I know that someday I will stop living; this does not bother me in the slightest. To proselytize to me by offering me some religious consolation to overcome my fear of death is therefore futile.
Although I do not fear being dead, I do not look forward to dying. Pain, illness, and frustration are a significant part of living; I expect they are an even more significant part of dying.
