That's the problem with some Palestinians. Their hatred for anything Israeli blinds them. In this case they will root for an organization that has helped starve Palestinian to death in refugee camps in Syria. The same regime that helps genocide their Sunni Arab brothers in Syria in the thousands.
Some of them think that the entire ME evolves around the Israeli-Palestine conflict and that every Muslim state in the ME is able to team up and attack Israel while each and every state has different goals. Be it Egypt, Turkey, Iran, KSA, GCC etc. None of those entities are ever going to attack Israel. So when that is not going to happen the only alternative is to support "resistance groups" (read proxies of state x or y) that will never stand a chance and which do more harm for Palestine as a whole and the region.
I can't phantom how any sane Palestinian can support Hezbollah knowing what has been going on with Palestinians in Syria at the hand of the Al-Asshead regime and what is going on in Syria in general.
Also tiny Southern Lebanon is practically outside of Lebanese jurisdiction. As I said then it's Hezbollah's personal fiefdom. That's all they care about.
All that "resistance nonsense" is what it is. Nonsense. There are very few genuine struggles left.
The biggest struggle is actually for the ME to be blessed with better leaders and for the people to achieve more rights. That's the biggest resistance struggle.
