Contrary to the argument that an ignoramus is someone who Googles Ignoramus to find out what it means, and ignoramus is someone who never Googles anything. It's someone who could know the answers to questions, but chooses instead to remain ignorant. As an added caveat, the true ignoramus not only chooses to remain ignorant but also actively seeks to ridicule the truth.

As in Gretchen Carlson is an ignoramus because she didn't know what ignoramus meant, so she looked it up online and said it is an ignorant lawyer.

Gretchen Carlson is too fucking stupid to know a simple word a 10 year old could figure out, and also too fucking stupid to look up the proper fucking definition... again... something a 10 year old could do. Gretchen Carlson is therefore an ignoramus and too fucking stupid to exist.
