Should tribal jokes be given space in our society?

I am always perturbed whenever I come across tribal jokes which dominate most of the chats in most social media platforms. These jokes although humorous are demeaning the target tribe. Could these jokes be slowly promoting tribalism? Or are they of any value to our society?

Take for instance a Luo who have a 24 inch plasma screen and a Mercedes benze outside his old grass thatched hut. The joke sends a message that they are extravagant and poor investors. And it also sends the message of poverty among the Luo community. While Maina,Kiprop or Kituva will be bursting into laughter , Otieno who the joke targets his tribe will get exasperated and will develop hatred toward other tribes.
