Well, you might've guessed correctly about me, geoff. I would have ignored it completely, but that it was brought to my attention by someone else, who simultaneously described the Euston document as "long and self-important".
Which it is. And it is largely irrelevant, especially to me. See both Mary Anne's and Robert's replies for better statements of why: like her, the Bill of Rights is all the manifesto I need as a liberal American; like him, I resent being dragged into the tiresome game of painting myself with the Soviet tarbrush merely to denounce it.
In other words, I am not an intellectual Leftist, I am a practicing liberal.
