One such country comes to mind is that of Malawi.
Only one political party existed there at a time,,,I'm not sure if that is still the case or what but.....
You were expected to carry a political card with you,,,,even with only one political party in charge.
But,,,JWs were prohibited from even carrying a political card with them,,,,even with only one political party. Resulting all kinds of persecution,,,atrocities & horror stories!!!!
