The protesters are full of energy, free time (no job?), and get spun up by whatever news source is influencing them. No, it really doesn't change anything. They are full of emotion, but lack critical thinking skills.
I would love to ask some of them about why they give a damn about the Palestinians.
There are a few points worth making:
Why does the rest of the Arab world dislike them or only exploit them for their own interests?
Why support a people who hate the United States and our ally, Israel?
Why support a people who have failed over the last 60 years to make something of themselves as far as economic or a functioning society?
Why do the Palestinian people always cause huge problems when host countries take them in?
Why support a people who have a terrorist government that attacks a superior military power that also is necessary for their trade, utilities, and so on?
It seems to me that the Palestinians are only good at complaining and not achieving anything in their territory that could be considered successful. They have tons of kids, live in poverty, waste all aid given to them, and then launch terrorist attacks against Israel. I have little sympathy for them as a people. Not only do they contribute nothing to the world, they cause endless problems.
