The words they were forced to say aren't important... it's what's in their heart that matters. I don't see that they sacrificed their beliefs at all, since they didn't really convert to Islam. I don't hardly think Centanni and Wiig are going to suddenly start carrying Korans and planning suicide bombings.
Similarly, moral people are against killing others, but there is a moral justification for killing in defense and in war. This is war and they were defending themselves, with words instead of bullets.
I agree.. somehow I believe this moment was God's Will so that Christians don't forget who we are fighting, and what we are fighting for. In my opinion this spells out clear and loud what the future will be under Islamic law: convertion or death.. hardly something we want for our children or grandchildren. We need to deal Islam a decisive blow just like we did with to the Japanase in WWII. Only then will they think about consequences in an objective manner and decide if the price can easily absorved.
