Does the Holder v. Humanitarian Law Project decision make the U.S. a Fascist Police-State?

Tough words, but read Gonzalo Lira's guest post in Naked Capitalism. Here's the summary paragraph.

[In its decision in Holder v. Humanitarian Law Project the Supreme Court decided that the] U.S. government can decide unilaterally who is a terrorist organization and who is not. Anyone speaking to such a designated terrorist group is “providing material support” to the terrorists—and is therefore subject to prosecution at the discretion of the U.S. government.
