People can push one way and then, once they’ve pushed too far, other people push back toward the middle ground.
This happens when the left or the right push past the centre, more than they should. Like a rubber band, the tension increases the further it’s pushed beyond its resting point. Eventually it snaps back or breaks. Neither is a good ending.
This occurs on any discussion. Everyone will be fine if small steps are taken. But if people push too far beyond the comfort zone of the others, you will find a great deal of resistance. And that often leads to momentum in the opposite direction. Keep things sensible. Or you’ll feel the backlash.
