Well, regardless of what the right answer is according to the poll, it is TRUE that people are stupid. There are many that are always stupid and quite enough who have significant DUH moments arranged in such a way that it causes problems. Then, there are the the smart who have best laid plans that go to shit because of a tiny - yet perhaps understandable - flaw in the works.
None of that is entirely relevent to the discussion at hand. I just thought that was an interesting bit of thought right there.
OT: I can boil it down, though.
Some people can't be arsed to take responsibility, so there.
Some people don't want to be caught, told, and then punished.
Some people are full of shit up to their eyeballs, even fooling themselves.
Still more ARE, in fact, freakin' morons. It happens.
Others yet have an agenda where they want to cause trouble for another instead of themselves.
And finally...there are those who are actually - gasp and shock - NOT TO BLAME. As general as this thread is, I think I've covered enough of the bases, but yes...it must be understood that some people are NOT at fault. Weird...
