The title is subtle clickbait, leading some to think the article might be an example of a black writer acknowledging a truth. But no, it was just another pile of 'woke' drivel. What you are is a flagellant (aka millennarian): these were members of extreme religious sects who, in anticipation of the millennium predicted in the Bible's Book of Revelations, would run through the streets naked, whipping themselves with leather thongs to 'purge their sins,' through pain before that bit where the clothes of the pure fall off and they float up to heaven (the pure not their clothes which would not have been pure as laundry facilities in those days left a lot to be desired.).
Whatever turns you on, but don't expect all of us to join you. Some of us actually know what "racist" really means.
BTW if you want to witness real racism go to Africa, Nigeria is a good place to start, you might witness Boko Haram thus carrying out one of their ethnic cleansing raids on a village of a Christian tribe. One of their favourite tricks is to make twenty or so men and boys lie on the ground, pour petrol on them and light it.
