Ex Muslim somali spaces tend to attract a lot of the outliers within our community. I don't know why your surprised I met a few Somali Christians.
I literally have no reason to lie about this. Somali Christians literally hop on TikTok live and talk about Christianity.
You can even find them on YouTube
I think what @Galool is saying is that, there is no sizeable number of them like AbdiFreedom makes it out to be.
Despite seeing a handful of them online, they live hidden life outside the internet and around Somalis.
It is easy to see why, no one would risk ex-communication and be social cut off from other Somalis. Plus you are trying to do the impossible by battling against Islam which has a close attachment to Somali identity and culture, to the point you cannot even separate it.
