Which voices are given credence here? Is the whole purpose of the book to argue against a slice of a broader ideological group or implicitly to pretend that all members than lean towards left wing policies support this no dialogue, victimhood approach? Voices like Ezra Klein and Barack Obama who are clearly left leaning, are not against dialogue, and definitely not against destruction of the whole system, and I’d argue they have a lot more influence and weight than the voices of the left that Shapiro is referring to here
