Coulter has been going after Adelson and Zuckerberg on immigration. I think that she is infected by grievances and has been spending too much time reading her friends at VDare.com, some of whom have a problem with Jews, or have a puerile interest in attacking Jews or Israel as a revenge on leftist Jews, many of whom don’t care about Israel.
Meanwhile the dissident right as a whole has been infected by the cuckservative trend of childishness and grievance. Cuckservative is short for cuckold conservative. It was started by white nationalists, who believe that conservatives are standing by as a non-white America is being created. Because it originated with white nationalist, the term has been used not only to attack open-borders and pro-immigration people, but has taken on an openly antisemitic tone. For too many, any support of Israel is cuckservatism.
Of course, rational people supporting lower immigration and buildign a wall would not post screeds about the need fo rIsrael to be diversified, or claim that Americans who support Israel are cuckservatives. Rather they would suggest that we follow the example of Israel. Grievance is destroys rational thought. Antisemitism rots the mind and soul. Coulter should apologize and grow up.
Cuckservative, I like the term they way you presented it.
