When you have a protest, part of the goal is to convience others not part of your group that your cause is correct. This can be a hard thing to do epsecially when you are inconveniencing others.
If you cannot convience outsiders that your cause is correct, your protest has failed and you just become a blocker of traffic making people late to work and conviencing people that your cause is correct is YOUR job, not the people who are on the outside. Nobody said its easy.
Using the block party analogy, Blocking the street for a block party is actualy not so popular anymore, but if you invite people to your party, they might be convienced to change their mind
The protesters in Israel need to learn how to convience outsiders that their cause is correct and that includes not only blocking the streets, but have people on the sidewalks giving and flyers and talking to people why they are correct, going on the TV news or whatever and giving interviews about their cause.
