African-Americans have had a history full of dismal and pain, whereby they were discriminated against and characterized based on their colour. Fortunately, generations have past and civilisations have improved, such that this very group of people who were once considered the lower class, hold many of the elite positions in the world. However some people still believe that some form of discrimination still prevails, in this case, by calling an african-american "Black".
Timaya's persuasive view on how african-americans shouldn't be called "Blacks" is rather powerful due to the way he brings his messsge across. Firstly, he has a convincing tone with different variations throughout the whole video, which engrosses the audience and increases their curiosity. Secondly, he uses Logos(logical content) to support his stand. He provides us with the obvious fact that African-americans are infact a shade of brown instead of black and that "Black" is another word for Negro, which in turn is a forbidden name to call an African-american. These proof add confidence and reliability in the attempt to convince the viewer.
This is an example of the interactive model of communication where, communication is a two way process of message between active senders and receivers. The audience are allowed to give feedback and exchange ideas. However, this process is sequential and there is a time lapse between message and feedback.
