But, in the 24th century, how is Captain Solok's attitude in "Take Me Out to the Holosuite" even remotely acceptable? Heck, even today, someone who wrote numerous papers about the inferiority of another race would be marginalized and seen as a joke. But Solok, who almost makes the xenophobic Cardassians look accepting, can do all the things Sisko described from their past and then, as a captain, bait a fellow officer with racist insults ... and it's accepted?
That's because there is no such thing as different human races
, and sexes aren't factually inferior.
How many papers are out there about the differences (and perhaps inferiority) of monkeys compared to humans? Even if monkeys could talk and solve trigonomic equations, there would be hundreds or thousands of scientific articles about the differences to humans.
Usually, a cold logical analysis evokes anger. Just try discussing with Christopher Bennett while having a different opinion than he has. He will academically beat you up and you will get so angry that he is right.
