That is a REAL deterrent. Of course, those who do speak out receive no press coverage within the MSM because they actually blame the terrorists themselves instead of Bush or the US.
The clergy within my wife’s sect did speak out against killing people via suicide bombers in the name of God by stating that they were not going to heaven for their evil deeds. The government of Iran rewarded them by systematically desecrating the burial sites of the Muslim clergy within my wife’s sect because they did speak out against such violence. My wife’s Muslim sect was declared ILLEGAL by the government of Iran. She had to live with this so called “crap” every day of her life.
This can also apply to those that are no longer living in the old country. If they speak out, their family and loved ones in the old country are also at risk of violent persecution. It is not “crap” it is very REAL.
Having said this, they are just going to have to get over this fear because, people in the US will automatically condemn them for their silence as you just did. They are screwed either way so, they should just bite the bullet and start speaking out more and in ways that goes around the MSM’s efforts to block them out of the news.
