You cannot support the Palestinians, just as you cannot support slaves, just as you cannot support the oppressed. What you can support is the resistance to oppression, slavery etc.
Manners is a concept invented by the oppressor, to regulate the oppressed. It is used to regulate the tone of any objection to oppression.
That way, if the oppressed got too emotional or uppity about his circumstance, the oppressor could indignantly protest the unmannerly and disgusting behavior of the uppity n***er/Sand N****r/moon worshiper or … whatever! People only tut tut when the oppressor is merely impolite. He really has to get seriously murderous before the slightest possibility exists for voices to be raised in protest.
It is instructive that people who successfully throw off their chains, are always the really, really impolite ones ; bombers, killers, really rude people
The revolutionary black rebellion in in South Africa rejected the participation of white revolutionaries, despite the ANC policy of Inclusion. The ANC Failed in their efforts, ongoing over a period of some 70 Years, even though they became the mainstream inheritors of the leadership of the transition of power, and gained great legitimacy amongst all population groups.
It is also instructive that the most successful resistance movement in the ARAB world, is Hezbollah, who have no Jewish Solidarity movement!!
This movement needs a little less guidance from the rebellious offspring of the Zionist movement giving Instructions. Abunimah should go on practicing his PC Chic, he may inherit the earth, but he is absolutely useless as a revolutionary. Revolutions eat their young. He is too sensitive to be one.
A Luta Continua!!!
