I'd say it's much more like blaming you for American terrorist actions (interestingly, I can't think of examples). Obama is the president of the country.
No, I don't think so. I'm the first to be down on American foreign policy, or just American culture in general, but this isn't the same things as terrorism. For one thing, it's the official state, not some randos.
With that being said, i get what these people are also saying. Equating palistine with hamas is like blaming me for obama droning a wedding.
Were these student groups actually supporting hamas or did they just identify with the people of palistine?
