It's the same reason why somalis would say syrians speaking af Somali are cute but cringe and get mad at Oromos in Somalia. Sure the colonial mentality is there but Kenyans are more afraid of millions of our folks running their country. A few white dudes isn't a big deal for them but millions of Somalis who have economic and political power is. The average Kenyan doesn't deal with Europeans , they deal with somalis daily and they see their neighbors from a gaajo country like Somalia (in their mind) opening malls , shops , getting rich etc and they get mad.
I'm not justifying their reaction, just explaining their thinking
