Summary
This quote suggests that a true Conservative is someone who actively removes outdated or decaying aspects from the existing system or structure. Rather than being rigidly resistant to change, a true Conservative recognizes the need for progress and reform. By metaphorically lopping off the moldered branch, they symbolically eliminate the elements that hinder growth and prevent improvement. It implies that a genuine Conservative is not bound by tradition alone, but is open to critical evaluation and willing to make necessary adjustments for the betterment of society.
