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?
Carter's views can't even be called antizionist. He plainly supports Israel's right to exist.
I don’t know how much is deliberate short term “winning the argument” vs how much people genuinely believe it, but it’s unfortunate for the majority of people who want to discuss issues under civil conditions. The second order effects are concerning, because this leaves public debate (ironically) to extremists, narcissists and manipulators.
