Most of the biggest tribalists in Kenya are first generation immigrants from gishagi to any city.
It's not their fault.
In the evening when they open the vernacular radio station all they hear is Uhuru is bad, Raira is bad, Ruto is bad et al.
The parents and neighbours have never seen a mujaruo in their lives other than Baba on KBC. They think all mujaruos look like baba. The same goes for the kalenjin warrior who has a political meeting where Keter shoots fire on their tribe being finished by Uhunye.
It's not their fault.
After living in your gishagi where the sharpest man was the village idiot and you come to the siiteh. You are too old to change your ways.
Blame all this to wiseman Moi who came up with quota system.
In our days, we got to see jaruos, kales et al in high school. Time enough to change your attitudes.
Now, these dot coms see mswahilis and Digos for their first time when in their 20's. That man-child is so stuck in his ways, he will be on Wazua talking about "others".
Ni mjinga tu na masomo haikumsaidia.Do the above experiment in your office today. Ask guys when they came to the city and you will see I have a working theoretical model.
Jose: If I make it through this thug life, I'll see you one day. The Lord is the only way to stop the hurt.
