(FOX NEWS) — A California professor is facing a backlash over a social media rant in which he calls Sen. John McCain, who is battling a brain tumor, a “war criminal.”

KGTV reports that those who have criticized San Diego State University professor Jonathan Graubart for his comments include students enrolled at the college.

“I find myself annoyed at the groundswell of good wishes for John McCain after his diagnosis of glioblastoma and have been thinking through why,” Graubart wrote on Facebook Friday, the same day McCain went public with the illness.

Graubart then made an analogy about elite lives and ordinary lives and circled back to McCain.

“McCain is a war criminal and, more to the point, someone who as a politician has championed horrifying actions and been lousy on state commitment to public health,” the professor said. “So dying or not, he’s a risible public figure (I have no idea what he is like on the personal level and don’t care).”

Graubart concluded by saying, “But ultimately what troubles me is the urge to send such well wishes to an utter stranger as it reinforces the notion that some lives are more important than others. There are lots of people with glioblastoma and who have died from it (including my mother 20 years ago).”
