(Actually, I disconnect my line at night nowadays.)
This is a better solution than the complicated and oppressive Do Not Call List.
What's oppressive about the Do Not Call List? Its only feature is essentially enabling citizens to disallow telemarketers from coming into their home.
The delusional bum apparently thinks that telemarketing is protected under the First Amendment. But as King demonstrated, invasion of privacy isn't protected under the Constitution. It's annoying, sometimes borderline harassment at times, and extremely disruptive to be repeatedly called by telemarketers whose "speech" is not Constitutionally protected. Furthermore, I don't like having to disconnect my telephone line - why should it be my responsibility and burden to block out annoying callers? In fact, I stopped disconnecting the line every night because there are certain people who may have a good reason to call (emergencies, et cetera), and it isn't fair that they should have to experience trouble reaching me simply because some idiot telemarketers won't leave me alone.
Bah humbug.
