Here's an e-mail I've received in response to an article about stopping doorstep sellers:
Please stop being so degrading about direct selling. Your article unfortunately comes across as rather ignorant considering cold calling is absolutely essential for any business to ever go anywhere. all you are doing is provoking slander and hate against very honest, open and happy people who are trying to make a living using the skills God gave them. Without selling of this nature the world would grind to a stand still.
