Dissent is the highest form of patriotism. I believe in this whole-heartedly.
And I appreciate anyone who has the gumption to protest despite their handicapped abilities to articulate what they oppose. Their right, and ours, to a freedom of speech is something few in this world can savor. Another right we should not forget to savor, though, is the right to mock them.
