Public discourse isn't the same as what happens when the media spins a narrative about a piece of legislation. You and I both know they don't need truth to make a story.
And small-time politicians looking to make a name for themselves will always impede the process, regardless of whether or not it's a good process.
Having the public voice their dissent is good. Letting a piece of legislation get ripped to shreds because some small-name representative has a hard-on for one of the bill's co-creators is not.
