Every part of the SS was engaged in ethnic cleansing and genocide, even the medical corp.

Only if you assume that all support for the institutions of the SS was in some indirect way ethnic cleansing and genocide.

How are you comparing them to Hezbollah, which only exists out of resistance to Israel’s ethnic cleansing of Lebanon?

Do I have to quote Hezbollah’s extensive history of antisemitism and calls for ethnic cleansing of Israel?

You haven’t made an argument for why they should not be considered non-conbatants

I quite literally did.

-According to Additional Protocol I to the Geneva Conventions, combatants are:

the armed forces of a party to a conflict, and also groups and units that are under a command responsible to that party for the conduct of its subordinates, even if that party is answerable to a government or an authority not recognized by an adverse party. Such armed forces shall be subject to an internal disciplinary system, which, inter alia, shall enforce compliance with the rules of international law applicable in armed conflict
