Nuclear Option on Filibusters

This article is a rebuttal for this article from the People for the American Way.

I'm still queasy about the nuclear option. The linked article from the Committee for Justice does sound quite reasonable. I'm getting tired of hearing that changing the filibuster rule with regards to judges is the stifling of debate. I don't understand that charge. A filibuster by its very definition is the stifling of debate.
