As opposed to petit mal.
I hope it was an isolated event, and that it won't affect his ability to serve on the SCOTUS. You can bet every ruling he makes from now on will generate a chorus of Dem accusations that he's suffered brain damage and can't serve effectively.
Some 25 years ago, while I was a teaching assistant at American University (DC) I happened to be talking to the professor in charge of the course about certain student who had petit mal. The professor stated that "everybody knows that people with epilepsy are retarded". I looked down to her, reminded her that I had a GPA of 4.0 and IQ of 140. I added that I had epilepsy, grand mal, and I took offense at her comments. Next I went to the department chairman and asked to be assigned to some other professor the following semester!
Since then I had heard many ignorant people make derogatory comments about people with epilepsy. But that was my first experience and it upset me more than I can describe with words. OTOH I went on to get a Ph.D. in molecular biology, publish a number of papers, get married, have children... currently I teach at a local college, convenient to my childrens' school. And, other than one 6-month stint without driving, I have pretty much done as I pleased... epilepsy or not. Justice Roberts may or may not have epilepsy, but it takes a democrat to think that it would interfere with his ability to do his job!
I wonder how Senator Johnson is doing in his recovery?
