Wait a minute, folks

In his speech in "Oh Brother, Where Art Thou?" Homer Stokes makes a speech about the main characters of the movie. The main characters were performing on stage a song they made up and recorded earlier, which became a hit, but no one knew who it was until then. The crowd and audience of the speech loved the band.

Homer was extremely ineffective at persuading his audience because he did not know them and thought he had credibility when he did not.

Homer proceeds to name things that the band had done against the law and that they should go to jail. The crowd proceeds to get angry and physically carry him out of the building. Homer did not understand his audience's point of view, and lost his credibility, by not appealing to the emotions of his audience. This caused him to lose respect and credibility. In the end, he tried to gain support by asking them "is you is, or is you ain't my constituency?" which made them question the support they gave him earlier in the movie, and finally lose all support and carry him out.

We can all learn from this, by acknowledging who our audience is, what their beliefs are, and how they feel emotionally about the topic we are presenting. If we already have support, we need to be careful not to lose it.
