Thank you Snopes once again...

I just received a forwarded email entitled "Don't buy it! Don't use it!  discouraging the purchasing of a supposedly new "Muslim" stamp issued by the U.S. postal service under the purported directive of Pres. Obama.  The email outlined a long list of offenses against the U.S. at the hands of "Muslims" and encouraged all patriotic Americans to protest such a stamp.   

If you check with Snopes there's only a vague resemblance of truth to the entire email.  There is a collector's stamp commemorating two Islamic holidays.  It was issued 9 years ago along with a collection of stamps centered around various holidays including Hanukkah, Kwanzza, Cinco de Mayo, Thanksgiving, Christmas etc.  It would be hard to boycott it as it is a specialty item which you have to request in order to purchase it.  It has nothing at all to do with Barrack Obama.  In fact, Pres. George W. Bush extended official greetings and participated in commemorations of these two Islamic holidays even after 9/11.  Seems as though it's just a gesture of civility in a diverse world.

So, my question is, who writes these emails?  How does such misinformation get spread around and about?  Why do thinking people so readily believe such propaganda?  Political leanings do strange things to otherwise nice human beings. 

P.S.  This is really strange.  I just went back into my email box to send the Snopes link to the person who sent me the email and the email has entirely disappeared.  ???
