The world is full of mindless sheep. I am sure amongst the members of PETA I can find a few room temperature IQs. I grew up a union democrat and was a mindless sheep donkey voter as was everyone around me, until I left my comfort zone and started interacting and learning the ideology of REAL liberals (or is it their theology).
Now as to your question, about being allowed to preach his beliefs, his 20 year colleagues from Honduras were executed in Iraq a few short years ago. Now before you get on the “one religion nutjob killing another” I only point this out to show that there are many Christian missionaries that do risk their lives all over the globe. Whether you think this is a waste of their time or not, isn’t important to them.
Now as to the major societies that have banned religion… China, Cuba, Soviet Union. Anything good about these places other than free health care from butchers?
