I actually think that "Allah is Satan", even if true, would have as much impact as you think. Many people already believe that. Has that belief had any effect on events? I don't think so.

I don't think the visitor is claiming the message will have any effect on the future--he is saying it will have a strong emotional content for people of the future everywhere.

The visitor is also saying that he does not believe that it would be easy to change the future because of practical issues--my example would be that persuading a liberal to see common sense is in most cases impossible! :-)

Usually it takes extraordinary trauma to do the job. :-(
