That's already been discussed, I recommend reading through the post histories of
@Xoriyo and
@haye haye who've contributed a wealth of analyses regarding our unique form of discrimination.
Those people also get attacked, but Somalis are the primary ethnicity in the Horn who get singled out for the sole reason that we have far too many traitors in our ranks who encourage the self-hating behaviours, which makes foreigners feel more comfortable outwardly attacking us.
I don't deny the impact of Islamophobia and have stressed it as a factor to the increase in anti-Somali sentiments online, but if the growing hatred of Islam was the main reason why, then we should have seen a parallel increase in anti-Sudani hate, as they’re not only viewed as an Black Muslim nation, but an Arabised one, fuelling the hate madows have for us. It would neatly be justified as "self-defense against the inherent anti-blackness of Arab/Islamic culture".
But, of course, that hasn't happened. Why? Because we (the young Western Somali diaspora) don't do a good enough job of making our digital image squeaky clean and often air out our own dirty laundry to boot.
