Whether the rule change will prove to be a good thing or not for the future, one thing is at least obvious to me, that we create what we fear. And since science has already proven that the conservative brain is more magnetized and affected by fear and disgust than liberal brains, we should be able to predict that it will be conservatives who will be acting in such a way as to create what they fear.
This notion, that we create what we fear, is known and has been known to students of the mind either in the area of religion or psychology, but isn't, I think commonly understood. I have described its workings elsewhere and won't do so again here. We see it in such expressions as, be careful what you wish for, or out of the fire into the frying pan, etc., so people often actually know what they don't actually realize what they know, but anyway.
What it seems, then, that Republicans have done is to fear liberal inspired change so greatly that they have gone to extremes in blocking it from happening. They have become so dogmatically adamant and have demonized liberals so greatly that they have destroyed the ability of the country's government as a whole to function. They believe this is a good thing, but the majority of the nation does not. Liberals, in effect, have been exhausted of their very considerable liberal patience, by fanatical efforts to stop any action they attempt by conservatives who believe they have a duty to do so. They have, essentially, backed up water so high behind a dam that the dam has failed. Now the water above the fracture lines will flow again and the folk with behind the will of the majority will be able to act out of their vision. The oak breaks where the willow bends. The wind is a natural force of nature that must be reckoned with. Conservatives have caused what they feared. They could not accommodate or compromise with the will of the people. They convinced themselves that the will of the people is evil and that an elite minority has the right to stymie that evil. This is the result of that part of conservative morality that responds to fear and disgust. They created the notion that they are to be feared and that they are disgusting by convincing the majority that what is to be feared and is disgusting, is them. To demonize others is to create that bed for yourself. All that is required is fanatical intention, true but irrational belief.
