Political Correctness has been on the rise for some time but seems to have been supercharged during Obama’s reign. This column explains how the overreach of PC Warriors hurt HRC and helped Trump:

The segment of the electorate who flocked to Trump because he positioned himself as “an icon of irreverent resistance to political correctness” think it means this: smug, entitled, elitist, privileged leftists jumping down the throats of ordinary folks who aren’t up-to-date on the latest requirements of progressive society.
Example: A lot of people think there are only two genders–boy and girl. Maybe they’re wrong. Maybe they should change that view. Maybe it’s insensitive to the trans community. Maybe it even flies in the face of modern social psychology. But people think it. Political correctness is the social force that holds them in contempt for that, or punishes them outright.
If you’re a leftist reading this, you probably think that’s stupid. You probably can’t understand why someone would get so bent out of shape about being told their words are hurtful. You probably think it’s not a big deal and these people need to get over themselves. Who’s the delicate snowflake now, huh? you’re probably thinking. I’m telling you: your failure to acknowledge this miscalculation and adjust your approach has delivered the country to Trump.
