Well said. Let's take it a step further:
I think a lot of people got tired of being told what they can, and cannot say... being lectured to by the "enlightened" ones. You can't say someone is "black", now they're African-American. What's next, we can't call women "women"? Are they now Breasted-American? Who made those rules? And why do we "have to follow them"? So somebody doesn't get offended? Show me in the Constitution where it says we have the right to not be offended. That is not protected. Speech is.
We Americans are an ornery lot, and tend to think for ourselves. If someone tells me I "can't say that!" guess what I'm going to say from morning to night, just to piss them off?
Sure, it's crude to say something derogatory. So let the idiot that says it feel the pain of his stupidity, rather than inventing some "rule" and forcing it on the rest of us. Erecting sets of rules to enforce your preferred worldview does nothing but expose you as a control freak, and people won't grow and learn from that... they just get bitter.
In the end, enough people were fed up with "political correctness" that they voted for the man that refuses to be "politically correct". Didn't the Left used to call that "speaking truth to power"?
A closing thought: people are speculating there were a LOT of "closet" Trump supporters that didn't talk about it. But they did vote. Why was that? Why didn't they talk about it?
Because they would be excoriated for the way they think.
Think about that for a minute. Since when did we let thought control creep into the common vernacular? Since when did it become acceptable for people to be publicly ridiculed for their opinions? Since when did "we, the people" give that level of control over our lives to someone else?
This turned out to be an election about personal choice, personal freedom and personal consequences. If you're going to act like an ass, then you'll feel the sting and learn to not be an ass. If you're going to risk doing great things, it's on you. Hope you succeed. But it's self regulation, not regulation imposed by others ... and that is what leads to maturity.
That is why the Gadsden flag was created. DON'T TREAD ON ME. It's the spirit of independence.
