So it took me a while to understand how the Afghanistan constitution can support freedom of religion, but still put that guy to death (Abdul Rahman - <http://www.msnbc.msn.com/id/11973510/>) for becoming a Christian. A news radio explanation filled me it (and now I will fill you in).
Apparently BEING a Christian is okay, and converting to Christianity from something other than Islam is okay. However, converting FROM Islam is a no-no. Not the act of conversion (which is protected), but in converting you are insulting Islam.
Insulting Islam is a capital offense.
Clear as mud. And obviously worth our on-going support in dollars and lives.
