This is the overall complaint about all things PC, and it's the heart of Donald Trump's complaint: We don't have time for feelings because we need to focus on getting shit done. After all, we have big problems in this world: war, hunger, slavery, torture, the economy, the black leather seats in my car get really hot, there's a fly hovering around my desk that won't go away, Twitter hashtags, and so on.
Even though that intuitively makes sense, because feelings are weak and weakness must be burned to fuel the fires of Our Great And Cruel Machine, science has found the opposite to be true. Turns out political correctness actually makes us more efficient: A study found that when you have a mixed-gender group of people who are given a problem to solve and asked to consider political correctness, they generate more ideas, and the ideas are more novel. Diversity makes us better at doing shit together. For a great example, check out how The Avengers were able to defeat Loki.
Even this guy had a purpose.
And these results extend beyond that one study: Looking at Wall Street, scientists found that markets with ethnic diversity tend to work better and more accurately than markets that are all white -- not because white people suck at Wall Streeting or whatever, but a bunch of people with different conceptions and backgrounds are better at getting things done than a bunch of clones of the same guy. Which, incidentally, is also why The Avengers were able to defeat Ultron.
Notice how they were helpless until the black guy showed up?
