I don’t understand the support for Hamas among some on the leftist. Of course, I understand that Israel has oppressed the Palestinians for many years and there is no justification for this, but there is no need to justify the actions of religious fanatics who also kill civilians, especially since Israel itself has aggravated the problem with the Islamists
Palestinian Marxists are unpopular there
Only because Israel has spent a ton of time and resources targeting marxists in particular. This is a huge chance for the PFLP and DFLP to build support
Did you have a point?
Marxists are almost universally unpopular everywhere except in a handful of countries (which few countries, incidentally, are almost universally hated by a big chunk of all the other countries).
