Progressive and facts are like oil and water. They don’t share the same space.
See my tagline......
As an engineer, my world is driven by facts. I make most of my work decisions based on the facts - the facts at hand. More often than not, the 'facts at hand' change...A more accurate reading is made...More data comes in and the statistical averages change...There was a calibration error...A different calculation method was used...Additional data channels are recorded..Etc.
I am accustomed to being wrong from my first decision and must quickly change it to become up to date. On average, I'm likely more often wrong than I am right. I'm quite used to that.
In the world of politics, few change their opinions easily. Opinions are usually based on ideology, not facts, anyway. People can rarely be conclusively PROVEN wrong. Many (example: resident Joe) will never even accept that they are wrong even when faced with overwhelming evidence. That's just life.
Progressives are even more prone to this. Most live in a sheltered world where alternative facts are simply unavailable. If your only news comes from CNN and NPR, and Facebook, the world of conservative facts is simply unavailable. They are quite unaware of what we know to be truth. Even worse, they're totally unwilling to find out. It doesn't help to try. They simply say 'goodbye'.
