God Allah and Muhammad

When someone come, and tell me he belive in God, Allah and Muhammad, no doubt it`s my right to tell him I tink he`s crasy, and when he tells about all the goodes in belive in that`s kind, I will tell him about all the bad tings, they who belive in that shit have done, and still do, But he`s say`s I have the books they wroght, how crasy can he be, All can sit down and wrigt pamflet like this.
