Tribalism is the natural consequences of democracy. If you want Kagame banning any tribal talk go ahead and ask for Rwanda type dictatorship. Under Moi dictatorship there was less tribalism and Kuria would be in a bad place if he dare say something like that then.
Democracy allows Kuria to say what he wants, for DPP to be free to charge him in court, and for an independent judiciary to determine if it's hate speech or not.
Our democracy is such that despite Kuria & Waitutu being Jubilee loyalist; they have been summoned by police and will probably be charged again. Moses Kuria and his lawyers will argue their case. Our judiciary led by stud man Mutunga will decide. That is all you want in democracy.
Kenya I repeat is more evidently democratic than TZ. And yeah democracy is not one variable thing (tribalism or lack of it). TZ is a country led by one party dictatorship that recently ban live coverage in parliament after CCM mps were found sleeping and drunk.
I find the democracy explanation too convoluted and long winding. An attempt to avoid owning up to the fact that there is a serious tribalism problem in Kenya, and the government has done nothing but feed the monster. It has nothing to do with freedom or democracy.
You mention Zambia as being more democratic than Kenya. How many Zambian Moses Kuria analogues have you ever heard of?
Tribalism for purposes of this discussion is negative ethnicity. Not mere existence ethnic groupings. It's ethnic hatred in the modern nation state. It is not the ethnic violence we see between Pokots, Marakwet, Turkanas, Toposa, Karamojong etc. Otherwise I could just mention them to easily debunk your theory without adding anything valuable to our understanding of the issue.
We still don't understand why Zambia, TZ, Uganda etc does not have a Moses Kuria, Waititu, Aladwa, Muthama, Ngunjiri etc. This sort of character last thrived under Habyarimana's Rwanda; a veritable dictatorship.
Rwanda under Habyarimana was one of the most tribalistic nations in Africa. Your theory says it should have been suppressed. Instead, massacres of Tutsis was routine. Was it a democratic place that we just weren't aware of? No. It was a space where state gave tribal loyalists carte blanche to spew tribal venom.
The better more relevant explanation for the Moses Kurias is that they have the blessings of the government. The government(as opposed to democracy) is feeding the monster.
