Those google workers were fired for defacing the google cloud offices and shouting threats at their coworkers, more than they were fired for protesting. Columbia University had to send in riot police because pro-Israeli and pro-Palestinian protestors were kicking off and the school had to close it's campus because it couldn't guarantee safety of students. The commencement speakers thing is probably the most egregious of those 3 things... but really is a graduation ceremony the appropriate avenue for making highly political statements on an issue that's incredibly divisive?
Either way, none of those examples demonstrate anything the US is doing because 1.) google isn't the US government, 2.) Columbia and USC aren't the US government, 3.) even the state funded universities in the US aren't the US government - they're funded by the states they reside in.
Is there any limit to the sort of bad behavior the zealots amongst the "globalise the intifada" crowd will tolerate for their cause? Is it not enough to call for perpetual bloodshed in the Middle East?
