"Xenophobic"? Hardly. But I'm interested as to why you think so. Is it because I notice the people on Slashdot that state that they hope the US is brought down, or destroyed, or otherwise weakened?
I don't recall that -1 Disagree was an option. Are you sure you understand the role of the moderator? In the past far too much negative moderation has been based on facts contradicting political ideology, with the facts losing the contest.
I don't defend everything the NSA does, I simply point out the facts. Many people make false claims about the law, current events, terrorism, national security, the founding of the country, and the role of intelligence in defending a free society. That something legal is also disagreeable seldom changes its legality. Denying the existence of a fact does not change it. Intelligence agencies can pose a potential danger to a free society, but that is not the same as genuine current oppression.
The truth is the truth, the facts are the facts. They don't change based on their popularity. Do even 10,000 people claiming a lie is true change it from a lie to the truth?
