Colossians 4, we are to walk in wisdom with outsisders and have grace in our speech. Yelling at people is not wise nor is it speaking to people graciously. We can make a good message sound very bad if we appear angry and deranged.

In cultures, times and places where such open air discourse is normal, than we should do it. Hyde Park is one example. People gather voluntarily to hear, they come to you....they are not harangued while helpllessly waiting for a light to change. The aeriopolis is another place...and Paul spoke there, and it was accepted for people to gather and hear open-air discourse.. At a cross-light in Manhattan perhaps not so much so.
