The real shame here is that she seems to mistakenly think her son is actively cutting her out. If she views Trump’s actions towards immigrants as defensible or even good, which is something that at this point is just utterly incompatible with the basics of civil society, then her own actions are forcing people away from her.
It’s sad to see people clinging to aspects of Trump, going down with the ship like this, still so lacking of self-awareness of the extreme degree of (not hyperbole) fascist violence inherent in Trump’s presidency, that she can’t realize this is entirely and unequivocally her own doing.
I wish we were still at a point where it was ideologically tractable to vote for Trump not because you like him but because of benign centrist Republican ideas, like generally lower taxes or states rights (regardless of the debates around these, at least they are legitimate, debatable aspects of the moderate Republican core).
But we are waaaay past that possibility, to the point where a vote for Trump that claims to be based on other innocuous, normal-time-debatable right-leaning issues is no longer that, and is literally (again, not hyperbole) a tacit vote for fascism and anti-science.
