Why are certain people blatantly being oppressed by the government (read details)?

I'm an anarchist. I will state that immediately, and I have no qualms about it at all. If you have any questions about how anarchy could work, there are tons of reference materials out there. Go research. Anyway, I recently came across this YouTube video.

I'm very concerned about this. Why are we, the people, allowing the government to oppress ANYONE? This is America, not Nazi Germany, for God's sake. The reader of these details and many others may not agree with anarchists; that is understandable, but what I'm concerned about is the oppression of opinion. Are we not a haven of free thought? Are we not a country that is supposed to accept ALL ideologies, regardless of whether or not we disagree with them? That's why we have ways to debate one another. That's why we HAVE A CONGRESS.

I'm becoming more and more concerned for the future of this country. No, people, Obama is NOT the only president guilty of letting this type of behavior slide. This has happened before, and I think it's going to get worse unless we do something. I'm supporting the Occupy Movement; it wants to curb the corruption of government. I agree with that sentiment; the situation has gotten out of control in this country, especially since the mid-20th century.
