I think half of is fear of violence; half of it love/admiration for Ruto; half of it economic mess anger - morphed into economic inequality/halve-nots versus dynasty; half of it fear of Raila.
You can choose and pick which one appeals to you - but definitely it a combination of admiration of ruto the person, the fear of Kalenjin going on a rampage on their people and knowing the police would not help, the anger against Uhuru and mt Kenya elite from the majority dealing with south-Africa like economic class divide, and of course the ever-presence railaphobia.
To therefore completely decouple Ruto - you need to address all those issues.
1) You need to assure Mt kenya people of their future in RV - where about a million of their people live - in an uneasy relationship with Rvs. This the Taboo Subject of 2022 - because apart from me - nobody talks about it. Everyone knows it an issue. RVs have gone deadly silent - from 1st term of Deni Lazima Ilipwa - to - HAMNA DENI

. Conspiracy of silence continues but it is big concern for Mt Kenya people living in RV. That is why they really hate Uhuru...for they know the drill.
2) You need to damage Ruto's character - Ruto is seen as a humble, dependable, and reachable Christian boy. You have more chance of success there if you also know Ruto is very corrupt. MOST propaganda was spent here - and it probably had the most success if you can call it that

until Uhuru family,ODM and Murathe were found with their hands-on CORONA (of all things) fund jar

. Kimwarer/Aror when compared to COVID billionaires relathieves - it is either a draw or Uhuru-Raila loses.
3) You need to respond to the hustler-dynastic economic/class divide - you need to find an extensional threat - that would unite Mt Kenya - so much they forget internal issues. You need to demonstrate that Ruto would be worse as an external threat - than whatever internal fissures. You need to stop banding around the sons and daughters of dynasties - and Uhuru need to rediscover his mojo - the one where he would drink Muratina.
4) Railaphobia/Luophobia - this can be easily counter-man by Kalenjin/Moiphobia. Ruguru threat is probably similar to many diehards Mt Kenya nationalist- R v R - ideally. But not now - maybe in the 2nd round when Mt Kenya nation has no option. For now they will ask why no go for Musyoka or MaDVD
This is why it almost hopeless to fight Ruto in Mt kenya

This is why four years late - most of them have given up.
I am not sure this truth is acceptable to Pundit. He believes the Kikuyu are at the mercy of the Kalenjin.
My own view: any anti-diaspora violence is more of a booby-trap against Ruto.
