Yes, 9/11 did wake up a lot of people, but not enough yet. There are still too many who view the pursuit of Islamic terrorists as racism. I wonder, as you do, however, how many more attacks will it take to wake up these other idiots? I would venture to guess, even a nuclear attack would not wake some of these dirt bags up. What do you think?
I suppose the death of one of your loved ones should be enough of a wake-up call for even idiots. The problem with the PC dirt bags is that they don't actually love anyone. So I think there is no hope for them: they will keep preaching PC right until they get nuked.
But the majority of Americans are--I hope--not PC dirt bags. Their thinking may have been influenced by PC propaganda to a degree, but the more evidence they see of what deadly consequences PC can have, the likelier they are to open their eyes.
Also, while older generations who have been brainwashed by the PC media are likely to continue believing the garbage, younger people will now be less susceptible to the propaganda. At least this is what I can see happening in my country, Hungary: older people, who grew up being taught about Marxism as the only legitimate worldview still buy the Leftist spin, however transparent it may be, but the majority of high-school and college-aged students are firmly on the RIGHT side.
