Do White Jamaicans Disrespect Jamaican Patois?

This white boy in the video demonstrating his knowledge of Jamaican patwah is a good thing, the problem I have with it, is the boy speaks in a quiet, measured  and calm voice  when reading English and suddenly  shouts and  gets angry when doing  the Jamaican  language. It reinforces  a negative stereotype which should  be avoided. It is conditioning and learned behaviour which is not right. Miss  Lou never showed anger when  speaking in Jamaican language.  Regards,  Tony Kelly
