You say so because you have never lived next to a group of gorilla fighters who infiltrate the boundaries and utilize your good relationship to kill your brothers and sisters!
The wall does not mean, Somalis, will not be allowed to come to Kenya, but they will now use official entries to minimize entry of Alshabaab in Kenya! Kenyan people and the Somalis are one, Alshabaab has tried so many times by bombing churches some years ago so that we Kenyans can start a fight between Christians and Muslims, but they failed terribly.
Kenyans are wiser, Kenyans will never fight according to their religion!!!
You can remember the Mandera instance, Muslims clinged on Christians and told Alshabaab, if it was to kill, they have to kill all!!
Kenya is one and Somalis are Kenyans, the only enemy is Alshabaab!!
