If anyone believes that Judaism is a religion that sincere folks can convert to, ask them why Palestinians are categorically prohibited from converting to Judaism "without review because of their ethnic origin":

Israel's authority handling conversions to Judaism rejects Palestinian applicants without review because of their ethnic origin, its head said.

Rabbi Yitzhak Peretz, director of the Israeli government’s Conversion Authority, spoke about his organization’s handling of requests by Palestinians to convert on Tuesday during a discussion on conversions at the State Control Committee of the Knesset, the Israeli parliament, the news site NRG reported.

To initiate an officially recognized conversion to Judaism in Israel, foreigners need to apply to the special cases panel of the Conversion Authority.

“The threshold requirements” to be considered by the special cases panel, he said, “are that applicants be sincere and that they are not foreign workers; infiltrators; Palestinian or illegally in the country.” In 2014, he added, the special cases committee received 400 applications. “Half of the applicants were accepted, the rest were rejected as foreign workers, infiltrators, illegal stayers and Palestinians,” he said.

Note: I'm not saying this is a bad thing. But Jews shouldn't be surprised when they are treated like "Palestinians" in Europe; European nation-states are homelands for preserving and promoting their particular ethnicity, they are ethno-states (or they should be soon). Jews and other ethnicities, folks who came in after WWII with no native blood, will not be allowed to "convert" to the native ethnicity. How can Jews argue this is unfair when this is what they do in their own homeland of Israel?

Note: I view ethnicities as spiritual as well as cultural-genetic entities (elevating ethnic identity to the spiritual level better ensures its survival; to see how this spirituality might be approached see: Aryanism as the Gateway to our Race-Soul).
