These Orthodox Jews have that Law in them and it works wrath, even against those who would lay down their life for Israel. Wrath because they have no covering for their sin and can only follow a set of Laws that their fathers couldn't even follow.
Faith in the death burial and resurrection will set them at liberty. The New testament is just words written on paper and burning it is hardly barbaric.
So would you be okay with Muhammadans gathering up Torah scrolls and burning them?
