Some sociologists who hated Christianity: Marx, Lenin, Hitler.

The MCAT tends to emphasize Conflict theory, Communism, and Marxism above alternatives. It would be hard for them to overtly promote Hitler, but Marx, Engels, and Lenin are no better.

Karl Marx (1818-1883)

Here is a whole book, Marx and Satan, written by Pastor Richard Wurmbrand, who was tortured by communists for not renouncing Jesus. It goes into Marx's imitation of Satan, and his desire to destroy God and make himself a god. It also mentions Hitler, Mussolini, Oscar Wilde, Nietzsche, Darwin, and more. Here are some quotes from Marx:

"I wish to avenge myself against the One who rules above ...”

"The idea of God is the keynote of a perverted civilization. It must be destroyed.”

 "With disdain I will throw my gauntlet /
Full in the face of the world, /
And see the collapse of this pygmy giant /
Whose fall will not stifle my ardour. /
Then will I wander godlike and victorious /
Through the ruins of the world /
And, giving my words an active force, /
I will feel equal to the Creator. "

Marx did not want to create a better society, he simply wanted to destroy it and laugh.

Vladimir Lenin (1870-1924)

"Atheism is a natural and inseparable part of Marxism, of the theory and practice of scientific socialism." - Religion, by Lenin

From this article by Prof Paul Johnson:

[Lenin] wrote to Maxim Gorky (13 January 1913): 'There can be nothing more abominable than religion'. He said he did not mind a corrupt and sinful priest-such were easily beaten. But he hated and feared the saints. The purer the religion, the more dangerous it was.

Adolf Hitler (1889-1945)

From this article by Dinesh D'Souza:

Hitler's Table Talk, a revealing collection of the Fuhrer's private opinions, assembled by a close aide during the war years, shows Hitler to be rabidly anti-religious. He called Christianity one of the great "scourges" of history, and said of the Germans, "Let's be the only people who are immunized against this disease." He promised that "through the peasantry we shall be able to destroy Christianity." In fact, he blamed the Jews for inventing Christianity. He also condemned Christianity for its opposition to evolution.

Hitler reserved special scorn for the Christian values of equality and compassion, which he identified with weakness. Hitler's leading advisers like Goebbels, Himmler, Heydrich and Bormann were atheists who hated religion and sought to eradicate its influence in Germany
