Most Latino activists I met are very much familiar with the struggle in Palestine and the Middle East, and they can draw strong parallels between us and them.
In pro-Palestinian marches you always find a good number of Latinos, usually coming as the second biggest contingent after the Arabs.
Familiarize yourself with the struggle in Latin America. We have common enemies: The US imperialists and the Zionists.
