To understand what happened...
1. Pick any three 'my personal betrayal by the world and what will I tell my beautiful, intelligent, strong yet venerable children about the state of society today' articles from today's Guardian.
2. Read them - every self-absorbed whiny word.
3. Think about them for a bit. Try to understand the astonishing levels of petulance, spite and the complete lack of balance. Imagine being stuck in a life with the authors of these pieces. Imagine how you'd feel if your children, despite your best efforts, turned out like this.
4. Ponder on why we've allowed such self-righteous vacuous idiots to set the agenda for so long.
Once the heaving has stopped, you'll be in a better position to understand why people voted Trump.
