There are numerous cities and towns that have enacted restrictions on door-to-door activities. This is a total and massive violation of our FIRST AMENDMENT rights of Freedom of Speech. People don't respect Freedom of Speech any more, since the definition has been broadened and weakened by allowing Freedom of "commercial" Speech in the form of billboards (which is bullshit as far as I'm concerned).
Our founding fathers were very intent on protecting freedom of political speech, freedom of personal speech, and freedom of association. Any restriction on door-to-door visitations would be a massive affront against all such rights.
What could be more philosophically consistent with Freedom of Speech than the right of a Democrat, Republican, or 3rd party representative to go door-to-door to promote their political party.
