As usual instead of confronting the issue you change the subject. According to this logic, how could you criticize the Palestinians when they attack Jews? After all, African warlords use much more gratuitous violence, as do the Chinese against Tibetans, as do many other peoples around the world. Obviously this doesn't justify Palestinian terrorism, just as lack of justice in Egyptian does not excuse, legitimate, or mitigate the actions of these Israeli civilians and the authorities who allow such practices to go unpunished and without investigation until the media and public shame force them to do so. If one can't complain about something if it is worse somewhere else in the world then the right should stop their whining about the UN, Palestinian terrorism , and everything else, since we can find worse examples of all of these things elsewhere in the world. If you can't justify your argument without saying "others are worse," then its not an argument worth making.
