I've generally gone to churches that are "evangelical" types, but I'd say that most of the people who go to those churches either accept the possibility that God could have used evolution as a tool for creation or definitely believe that it was his means of creation. Most of the people who don't are typically older. Either way, they don't get too upset if someone dares to disagree. They may give you that, "Oh, that poor idiot" look, but the feeling is probably mutual. ;)
My JW boyfriend says that he thinks it's a possibility evolution was the tool, but God actually expressly created Adam. So he doesn't follow that staunch creationism thought, either. There's hope for him yet! Just don't alert the elders...
