As a jew I really dislike my people. They are extremely smart on average, yet they are ridiculously stupid when it comes to common sense. Hence, they are liberals and their liberalism is going to get them killed.
First, bullies don't respect weakness and nuance, they respect strength. This isn't rocket science, it's common sense. Most people secretly want to impose their will on others, most don't because they don't want their ass kicked. If they think you are going to kick their ass (or at least make a fight unpleasant enough), they won't f*** with you.
But only liberal jews board a flotilla with PAINTBALL guns. What the f*** were they thinking? They were trying to be nuanced and respectful to people whose entire purpose was to be blunt and disrespectful. Nine people got killed because they weren't scared, because they saw paintball guns and thought they could be a bad ass and attack the commandos. I bet had the Israeli's had real guns, pointed directly at the protesters heads, and the protesters knew it, their bad assness would have gone away. How many of those nine would have done what they did if they knew that was their last day on earth. I'm betting less than nine.
All nuance and proportional force does is make it less costly for your enemies to continue to fight and in the long run, there will be more conflict and more death because of it. You want to prevent violence, you want peace, then you have to kick some serious ass. Unfortunately the Israeli's are a bunch of liberal jews and they are going to get themselves (and others) killed.
