I was born an American. Hezbollah is a group you have to choose to join. Accidents of birth and conscious choices to join a group with a violent ideology and a history of acting on it are so different, I find it hard to believe you would actually equate them.
Hezbollah is more akin to joining the KKK or Weather Underground.
