In this great country that I live on named U.S.A., we have the freedom to choose to be whatever we want, we can choose which religious path to take. It is our right and prerrogative. Believe me, like you, I did live under a military dictatorship in another country and I now know what freedom is.
It's true that there were histories of injustices in this country. However, you are only singling out the JW's. How about the Asian inmigrants? Most were not even allowed to become U.S. citizens at the beginning of the 20th century. The Chinese who worked on the West Coast Railroad were treated just as bad if not worse than the African slaves. The Japanese were in internment camps during WWII. It is a shame and injustice that those events happened.
You know what? Laws have been changed: JW's can choose to salute the flag though I know certainly they won't. People here can even burn the flag. It is still part of free speech. If JW kids do not pledge allegiance to the flag, that's fine. If they get beat up for it at school, you can still sue the school as you do have freedom to choose. Now let's see if within your congregation, you can have the freedom to question the teachings and doctrines of the society. If you get excommunicated for it, can you sue them for infringing your freedom?
