This already happens inside Israel.
Large numbers of young Jewish girls are groomed by much older Arab men. They are usually converted or just raped by the Arabs.
Actually 100s of Jewish girls convert to Islam every year, inside Israel, in order to take part in marriages to Arab men.
However, never in Israel's history, has a Muslim or Arab girl converted to Judaism (or ever been allowed to date a Jewish man).

However, in Israel, the media is dominated by leftists, and nobody raises this issue.
Actually it would take a grassroots effort to do anything about it.
