there is no law that says you must. Unless you live in any of the Muslim countries, those laws don't exist.
Exaggerate and lie much? In ANY of the Muslim countries? Try a few facts instead of your constant flow of bullshit.
apostasy is a crime in 16 out of 49 Muslim majority countries; in other Muslim nations such as Morocco, apostasy is not illegal but proselytizing to Muslims is. It is subject to the death penalty in some countries, such as Iran and Saudi Arabia, although executions for apostasy are rare.
