What do you mean by condescending to slander?

Don't be afraid of the slander of those little people, and don't be afraid of some people. The word "why bother condescending to be afraid of slanders" comes from Wang Anshi, a poet in the Song Dynasty, "Why bother condescending to be afraid of saying what is right?" It means that a person should do the right thing, not be a villain, do something humble, and be upright, so that he will not be afraid of the slander of those villains or the humility of some people.
