"I've never believed that the only way to make a dent is to be a table thumper"

In this quote, David Brudnoy is expressing his belief that making a distinction or creating an effect does not necessarily require being loud or powerful. He is rejecting the concept that one needs to be aggressive or confrontational in order to effect change. Instead, he suggests that there are other, more subtle methods to make a distinction. Brudnoy might be advocating for a more peaceful and diplomatic method to problem-solving, rather than resorting to aggressive tactics. This quote likewise indicates that a person can make a substantial effect through quieter, more thoughtful actions, rather than just being loud and powerful.
