How does Tom Buchanan from The Great Gatsby represent pseudo-intellectualism?

From the moment readers meet Tom Buchanan, we know that he
is a bully, an elitist, and arrogant. As Nick approaches Tom in Chapter 1, he describes
him as having a voice with "a touch of paternal contempt" and emitting the attitude
of

Now, don't
think my opinion on these matters is final, . . . just because I'm stronger and more of
a man that you
are.(11)

Similarly, when Tom
lapses into his spiel about Goddard's Rise of the Coloured Empires,
he tries to "school" the others at the table on his white supremacy
"knowledge" but is merely spewing out what he read. He tries to appear to be more
intelligent than Nick, Jordan, and Daisy by belittling Daisy and simplifying his
thoughts for Nick. Nick, of course, is too observant to be fooled and
thinks,

There
was something pathetic in [Tom's] concentration as if his complacency, more acute than
of old, was not enough for him any more.

Later, Tom's disdain for
the attendees at Gatsby's party not only represents his elitist attitude about social
classes but also demonstrates his insecurity around people who are ingenious enough to
earn money or talented enough to making a living from their skills.
He is archetype of humans who focus on one conversation point such as a book to try to
appear intellectual.
