I don’t know how “lunatic” this is. But this was an ad I just saw pop up, which is an amazing slap in the face to everyone who has worked for that title.
I have a JD. The degree you get from law school, at least here in the US.
The “D” literally stands for “doctor”… no one ever calls you doctor though.
Not that I use the degree any more. I work in IT now!
