These girls are just naive, truly boring people.
But should the JEWS proselytize if that means fighting against ISLAM? Westerners converting to Islam usually do so because of the trinity. They don't want to worship a man who's also the son of G-d, but then it doesn't cross their mind that Judaism also worships one G-d.
No proselytizing in Judaism.
All of the Biblical quotes relating to converts are clearly talking about the converts attaching hemselves to the people of Israel and the G-d of Israel, not being bamboozled into it by Missionaries.
But Jews SHOULD proselytise/teach the Seven Laws of Noah to the goyim.
