The idea that the human race will never exactly agree on what is "true" is correct and obvious.
The opinion expressed here that nothing has changed in the world recently about how truth and politics are handled is false. With the collapse of reasonable arbiters of "truth", such as network TV anchors, who were imperfect themselves but nevertheless served as a check on the falsehoods that a political party could put out, parties have discovered that 100% bullshit 100% of the time is a workable approach to politics, and some of them are pursuing that. That was never true before.
