Dear Danny I do not know what you mean by "anti-theists". If someone criticizes theism is she/he anti-theist? Suppose that she/he is; why we should not be anti-theists. If someone criticizes physicalism or materialism is she/he anti-physicalist or anti-materialist? If yes then why we should exclude theism? If no, then criticizing theism will not mean to be anti-theist, too.
