The resistance in Gaza is apparently Shia (Hamas and Islamic Jihad) and Communists (DFLP, PFLP, Al Aqsa Martyr’s Brigade, Popular Resistance Committees). Al Aqsa Marty’s Brigades is an offshoot of the PLO (disowned by them) and one of its stated principles is socialism. DFLP and PFLP are Marxist organizations. The Popular Resistance Committees are actually breakaways from the breakaway Al Aqsa Martyr’s Brigades, and as such have socialism as a goal.
The DFLP, PFLP, Al Aqsa Martyr’s Brigades and the Popular Resistance Committees are all relatively secular. Hamas is radical Islamist. They are the Palestinian branch of the Muslim Brotherhood, but they do not talk about this much because the MB is not very popular with relatively secular Palestinians. However, Hamas is not anti-Shia and they are mainly supported by Iran, Syria and Hezbollah. Islamic Jihad was founded at the time of the Iranian Revolution and was influenced by it. They have long been supported by Iran and even have training camps in Iran. A while back, one of their leaders actually converted to Shia Islam, causing a bit of a stir among Palestinians.
This Salafist is an idiot. There is no reason to refuse to support the Gaza resistance because they are Commies and Shia, and it’s not even true anyway. The hatred of the Shia is odd for an Egyptian. There are few to no Shia in Egypt, the rest of North Africa or anywhere in Africa for that matter. The Shia are mostly hated in places where they are a lot of them or close to places where there are a lot of them such as Arabia, Lebanon, Syria, Jordan, Turkey, Iraq, Yemen, Bahrain, Kuwait, Afghanistan, and Pakistan. Of those nations, only Jordan lacks a significant Shia population. Outside of these places, most Sunnis do not care much about Shia Muslims, probably because there are no Shia in their countries.
