The 51-year-old singer, who now goes by the name Shuhada' Davitt, even acknowledged that the sentiment she was about to express Tuesday is racist.
Announcing her conversion to Islam in October, O'Connor said it was the "natural conclusion of any intelligent theologian's journey".
"Dear Sister, whoever is "teaching" you about Islam, seems to be trying to lead you astray".
O'Connor began her Twitter rant by apologizing for saying "something so racist", explaining she never thought it was something she could ever feel. "But truly I never wanna spend time with white people again (if that's what non-muslims are called)", she tweeted.
She closed out by saying that "If it's insane to care... by all means, spank my ass and call me Fruity loops". Not for one moment, for any reason.
In a follow-up tweet, the Grammy-winning singer said it would be interesting to see if Twitter banned her while allowing people like US President Donald Trump to spew "satanic filth" on the platform.
While Davitt's Tweets generated a large amount of controversy from both fans and onlookers, she closed out her series of Tweets by noting how her critics will likely refer back to her previous struggles with mental illness. The Irish-born singer then took aim at Christian and Jewish theologians for glossing over their own faith's histories of religious violence, particularly targeting Trump supporters and her own home country of Ireland.
"Final word. If its "Crazy" to care".
