On the contrary, 'from the river to the sea' means exactly that - that israel should cease to exist and that Jews should not live there.
Again, you ignore the other chants 'globalise the intafada ' and 'by any means necessary '. What exactly do you think these mean?
I abhor all wars, all loss of innocent life. But this thread is specifically asking why people are fearful of the free Palestine movement. I'd wager jewish people are more fearful than most given most of the chants they shout are directed towards them (seeing as 90% of jewish people identify as zionists - ie: the right to self determination in their ancestral homeland. NB': that does not mean they cannot live side by side with their Arab, druze, Christian, copt and Muslim cousins - just as they have done for many years - Muslim Arabs I the judiciary, equal rights to education, work, pay, medicines etc)
I want nothing more than peace, but calling for violence globally against jewish people is not the answer.
