A strange thought I know, but being a freelance writer is a good example of Dr. King's dream. He dreamed of a person being judged by the content of a their character, not the color of their skin.
Most freelancers don't go have to drag out their good suit and show up for a person-person interview. There is little worry about being judged based on skin color, age, sex, religion or sexual orientation.
Freelance writers are judged by experience, skill and killer queries.
People often woe the dangers of the net and the ability for prejudice people to find like minds to express their rage and hate. And while the net does provide anonymous cover for butt heads, it also provides a blank slate for which people can write their own destinys. It provides information and resources that likely would have been closed to some people.
So stand proud fellow writers and keep King's dream alive.
