Personally, I think it is very legitimate to appeal to sentiments, because of the three means of persuasion (http://en.wikipedia.org/wiki/Rhetoric_%28Aristotle%29) pathos foremost agitates people to actions. And sometimes, it is necessary to act (and inform the public). That you disagree with others on this very issue is no reason for insult.
In Rome, do as the Romans. Simias's post has much more content than the video, and makes a self-contained argument. The link submitted presents a page with a video imploring us to... what.. share the video? Because it will make a difference? Why? Also, what are we making a difference in again? Why is the government a dictatorship? When did that happen? (I'm not asking, I'm saying the video doesn't answer any of the above questions, which are critical to the appeal for support)
