Peter Greenberger, a former Twitter and Google executive, is calling for the social media accounts of President Donald Trump to be shutdown for the remainder of the election. For those of us who have criticized calls for censorship from Democratic leaders for years, the demand is yet another example of the slippery slope of censorship that awaits this country with increasing regulation of speech on social media.

Congressional leaders like House Intelligence Committee Chair Adam Schiff have called for labeling and removal of material with some members directly threatening a legislative crackdown. Speaker Nancy Pelosi denounced Facebook CEO Mark Zuckerberg for resisting speech monitoring and censorship as a matter of free speech. Pelosi lashed out that those who want to preserve a free speech zone are "all about making money," ignoring free speech advocates who have no financial interest in these companies. Joe Biden has demanded that prior Trump criticism of mail-in voting be stripped from the Internet and social media. This is an effort to enlist companies like Twitter and Facebook to regulate political speech.

And it is increasingly succeeding.
