Exodus
Alienist
There are a few gay Somalis who tend to become Christian rather than Atheist/Agnostic that I've seen online.Most of them are likely former atheists who then still felt a need for religion, but were ''disturbed'' by Islam.
There's a segment of them who are self-haters and want to be more like white people/Westerners and therefore adopt Christianity.
And some probably are married to a Christian and converted for that reason.
I think those are the three main reasons.
