"But we must stick with a decision."
Substitute the word 'decision' with words such as: culture, tradition, the way things ought to be.
So many people don't challenge their assumptions - including me! We must challenge our assumptions with sound reason.
Epictetus responds to the person who says, "we must stick with a decision."
"For heaven's sake, man, that rule only applies to sound decisions. I suppose next you will decide that it is night now, and refuse to change your mind because you don't want to. You will repeat, 'We must stick with a decision.' Begin with a firm foundation; evaluate your decision to see if it is valid - then there will be a basis for this rigid resolve of yours. If your foundation is rotten or crumbling, not a thing should be built on it, and the bigger and grander you make it, the sooner it will collapse."
