Yes - they demonstrate Palestinian solidarity and a genuine commitment to non-violence.They shot and killed them when they did a non-violent demonstration if they got too close to the border fence. Slaughtered them in their dozens.
Non-violent demonstrations in prisons also tend not to work very well.
Seriously, you think if you were living in Gaza you think there would be any point at all in doing a non-violent demonstration?
No fantasy land - real world reports suggest that the peaceful protest which was away from the border fence became violent when some protestors splintered off and moved towards the border fence, hurling abuse, throwing rocks and Molotov's.They sat down nowhere near the border fence, but the Israelis shot them anyway for being too close.
You're living in a fantasy land.
Of course, this didn't justify the proportionality of Israeli's response, but my point was that it was no longer a 'non-violent' demonstration at that point.
