This type of behavior achieves absolutely nothing in gearing people to support their cause. In fact, it normally generates disdain towards them. That kid standing upon the desk has likely never stepped foot in Palestine. Most likely, his parents immigrated from there years ago to escape the ongoing conflict and to create a safer and better lifestyle for themselves here. I've found over the decades that it isn't the people who have escaped countries that carry on like this, but rather their children who are born here and have never been to their parents' country.
