The important thing is to voice your disapproval. I'm confident that my wording could be improved, but it's important that Obama quantify the sheer number of US citizens that disagree with this despicable act.
The important thing is to voice your disapproval in a manner that a) identifies the issue and b) identifies your stance on the issue. Your comment misses the mark on a) by being down right wrong, and your stance on b) comes across as you believing you know more about these matters than the people executing them. The fact that you come across that way without having a clear understanding of the issue is going to lead them to dismissing your disapproval.
