If you are thinking of leaving Islam, be wary, be careful. Do not tell your Muslim friends or family. The Qur'an commands your death for leaving Islam (4:89 calls for the murder of renegades from the faith), and Muhammad is explicit in a hadith: "If anyone changes his religion, kill him" (Bukhari). Many, many 'honor killings' have been committed for "crimes" that are in Islamic law considered far less serious than leaving Islam.
Think you're safe in America? Rifqa Bary has been threatened numerous times for leaving Islam. Rashad Khalifa was murdered by Islamic supremacists in Arizona in the early 1990s -- because of his "heretical" teachings. If you doubt that you're in danger in America, be aware that apostates have been threatened or murdered in recent years in Afghanistan, Egypt, Pakistan, Somalia and elsewhere. It doesn't matter how free or open your country's society is: the law of Islam recognizes no national borders.
If you fear for your life, contact email@example.com. If you are unsure of how your family or community will respond to your admitting that you're leaving, don't take chances. Write to Pamela Geller at firstname.lastname@example.org or Robert Spencer at email@example.com. If you need immediate protection from a threat, call the police immediately.
