That link doesn't seem to support your claim that Carter wants to erase Israel.
The link describes what a bunch of white supremacists think about the book. Some (many?) of them likely haven't read it, and are reacting to the title alone.
I will admit that I also haven't read it. But I know it contains this paragraph:
> The security of Israel must be guaranteed. The Arabs must acknowledge openly and specifically that Israel is a reality and has a right to exist in peace, behind secure and recognized borders, and with a firm Arab pledge to terminate any further acts of violence against the legally constituted nation of Israel.
That doesn't sound like erasing to me?
