No one is threatening violence. But it could be a consequence. Also as you agree tribal clashes did not start with Ruto. Indeed the whole issue is a bit more complex than you think.
I personally have been involved in pro bono cases trying to have victims of this violence compensated. Even right now am involved in some case whereby there is a court order to freeze 7B because MOST OF GOVERNMENT DECLARED COMPENSATION have gone to fictitious IDPs. And this is facilitate even by "own" Kikuyus. Including senior leaders and prove exists. You'd expect a Government led by Kibaki and then Uhuru would have finalized this IDP issue and resettled people. But they really don't care that much.
Then you need to put 2007/08 clashes into context. No one is an angle here. If it's comparing Ruto and Raila for example you'd realize they both bear responsibility for 07/08. Indeed that when everyone ganged up against Kikuyu whether one was in Western or Coast or Rift Valley. The ethnic undertones were obviously infamous "41 vs 1"... Pure incitements. So who should take most blame? Who's angel here?
I was also in those Nakuru meetings and others when "reconciliation" were discussed and dealt with. Remember reconciliation was/is between communities and Ruto/Uhuru were merely leading that process at that time and now.
Unfortunately political disputes and tensions have the tendency to bring the worst relations between communities. Especially between Kikuyu/Luos, Kikuyu/Kales. These are the hazards and challenges of a multi ethnic society. I too don't have magic bullet to resolve all these.
BBI on the other hand is actually premised on ACCEPTANCE OF ELECTION RESULTS. They are claims of biased or compromised electoral body or straight out rigging. And to deal with this a lot of reforms have been adopted by somehow some people are never satisfied. It's as if everyone (every political competitor) need to be accommodated into the government. Maybe we should form something like Chinese System or Soviet Politburo instead of competitive elections..
What's the use of asking for forgiveness when threatening to unleash violence if he is not supported in 2022? What kind of forgiveness was that? You say you are on the ground. I also know a number of Kikuyus who have never regained their lost properties in RV since 92, 2007. have you met any of them on the ground?
