You mean those Moslem missionaries with swords. That's a real heartfelt conversion they achieved.
Believe in Al-Ilah or lose your head. And if you ever want to leave...leave your severed head with us.
Now that's a religion!
The only way you have a chance is if you understand where they're coming from. Then you can chase them away just like they were Mormons or Jehovah's Witness missionaries.
