I'm a fellow athiest and I stutter. I have come to learn and accept that God had nothing to do with my stutter. My stutter is simply a combination of a nurological disorder enhanced by social anxiety. There is no reason to be angry, no reason to lash out. Some people are born with less fingers, others mental disabilities, we just happen to talk different. It's not that bad. I used to be a Catholic and I prayed to God every night to remove this curse. I stopped believing partly because I never received any answer, but mostly because I got really into science and started educating myself on different religions and realized none made any logical sense to me. Atheism helped me break free from the torture of thinking it was something done to me and I am able to accept it's just a part of who I am. We have to make the best of it in the short time we have here on this earth. There are benefits as well as flaws with everything in the universe. I still stutter but I am more accepting of it than I ever have been, or could have been with religion in my life.
