You're right, their intent is the same, an end to the systemic supremacy and human rights abuses of living under an Apartheid Regime. Hamas began twenty years into the occupation during the first Intifada, with the goal of ending the occupation. Collective punishment has been a deliberate Israeli tactic for decades with the Dahiya doctrine. Violence such as suicide bombings and rockets escalated in response to Israeli enforcement of the occupation and apartheid.
Israel is the one that intentionally conflates the two in order to deflect from criticizm. When Israel commits war crimes, or human rights abuses, or land grabbing, they are the ones that claim they do so for all Jewish people. When Zionist actions are criticized, they call it antisemitic. The conflation of the two is genuinely antisemitic, as the actions of Israel in no way represent all Jewish people.
If you don't want to be naive, I suggest you read the reports by human rights organizations.
