They blocked a personal friend of the late Arthur Miller. What is this world coming to? ;) This post made me curious to research the reasons you "threatened violence"
A quote from Miller in that article could apply to the situation today! I live in Cambridge. Let me know that lucky spot I should sit ;)
"Like many others I am very disappointed with Clinton even as I recognize that he is caught between his weak constituency and the Right, which has absolutely no program but can still put on a show of patriotic strength. [] The Bosnian catastrophe is probably the signifying event of the time – everyone knows it is evil and no one has the rationale to intervene in any creative way. It seems like an event without a principle – like a collision of asteroids whose broken fragments may fall on us and kill people, but what is to be done?”
Really, blocking you, this is just TOO funny!
