People usually hate what they do not understand. How to communicate in clear and simple english, how to debate an issue without resorting to abusive language and name calling, the idea that individual liberty is what America was founded on, acting like a mature adult rather than a spoiled child, dealing with the inner conflict of having voted for someone who clearly lied to them... it's important to learn from our mistakes. If we do not contemplate our own shortcomings, how would we ever grow? Sadly, some cannot bring themselves to admit failure and carry on believing the lie.
"Men occasionally stumble over the truth, but most of them pick themselves up and hurry off as if nothing had happened." Winston Churchill
