It's like when 2 people with different languages were to meet up in a forest and had to communicate, the first thing they would do is try to establish a common word, probably "tree" or something. Tree is this word, and then they would move on to a second word. But our society won't agree on tree, we point to a tree, they say racism. We point to a rock, they say racism (as we know, the only thing the left knows is racism, and is the only thing they think about). We cannot establish a baseline of communication, because they won't agree that a tree is a tree.
And now to the eventual solution, which will not be a good thing in many respects, but will be here...very soon you will have an app on your phone that will tell you with very high accuracy if someone is lying to you or not based on their facial expression, tone of voice, choice of words, etc. You will be able to ask one of these crazy people if a man is really a woman, and the app will probably say they are lying, and they won't be able to do anything about it, except make fake apps that say they are lie detectors but are actually not, and try to sell that to the public as real. But for a while, we will have truth and lies easily detectable, and people will agree on reality, even if they won't want to or refuse to admit it, at least we will know. It will also cause lots of problems, for instance when the wife asks if she looks fat in that dress, she will whip that app out on you and your marriage will end. There will be sad results. But lie detection technology is the best way to establish objective reality between people.
This is the inevitability of solipsism.
When nothing has meaning or significance, there can be never be agreement.
