Theres a bunch of factors that go into good protests. Stuff like a single unified message (Occupy Wallstreet), good visibility (any random protest on a random street corner), a position that isnt stupid (The proud boys), if the media likes you, and probably a bunch more.
The key problem with Israel vs Palestine is that Israel is western, works with Nato, is in the UN, doesnt execute rape victims, doesnt execute gay people, claims keep coming true, etc.
Palestine on the other hand, is 99% Sunni Muslim for a very nasty reason.
Its a very dumb and uninformed position, spread by genodical maniacs.
