I think I would rather live in a society that guarantees freedom of expression and religion than one that legislates against it. There are many things that are annoying in life. But do we want to restrict other people's rights just to assure our own comfort? After all, some people are glad to have JWs, Mormons or Adventists call. Personally, I would rather take other measures such as requesting JWs not to call on my home any more or to put a sign up saying that JWs are not welcomed.
Personal freedoms are precious. We want to be sure we don't restrict the rights of other individuals just to convenience ourselves.
