I tend not to revisit my past replies, but I'll make an exception here.
You're right. Those people are probably expressing genuine remorse, because they've been brainwashed. Does anyone honestly believe that the same thing isn't happening in our own country? Do people think their beliefs have any basis in fact, or are we merely basing our decisions on 'facts' that have been fed to us by the media? Media that's paid for, and controlled by the people who stand to gain from its content?
Do we honestly believe we're less susceptible to brainwashing than those 'poor brainwashed people' in North Korea? We only 'know' what we're allowed to know. How are we any different to the North Koreans?
Just a thought...
