It's not jewish. Where is the evidence that it's jewish? ONA, like JoS is National Socialist and rejects everything Abrahamic in relation to Satanism, like their Qliphoth and jewish grimoires. They also define Satan as the Enemy of the Jews.
Their methods are misguided and dangerous, but they are not in any way related to jews.
Jewish "Satanic" organizations are the opposite of ONA: they are against National Socialism (and often promote marxism and communism), they glorify jews and they sometimes falsely claim jews are "Satanic". I ran into such a group in the past, where a self-proclaimed "Satanic" High Priest in his Yahoo groups banned everyone who attacked the jews using the excuse that "we are only against the christians and jews aren't christians".
