You have a hard time buying into it because the thinking is neither straight nor clear. It is hopelessly flawed logic. There is actually a bona fide name for that type of skewed illogic, but it's been too long for me to remember it.
What IS true is that "openly discussing" this issue with facts is not politically correct. It's like criticizing Israel. Fingers will be pointed, accusations of bigotry and racism will be launched at the discussers, labels will be freely applied and the hate-name will be liberally and relentlessly used by those who disagree with the discussers.
THAT is why there is silence.
The MinuteMen don't care about labels, pointed fingers, accusations of whatever and hate-names. SO MANY are Vietnam vets and .... well, they just don't care what anyone else says; they are going to do what they believe and KNOW is right. The hell with P.C. I love'em.
I know what you're saying. There are a lot of things that can't be sadi anymore due to political correctness. It's real bad where I work, a large company.
