No doubt, the johns are NOT regarded as "immoral"

Activists in Bangladesh have welcomed the first ever Islamic funeral for a sex worker, breaking a long-standing taboo in the Muslim majority nation. Hamida Begum, who worked at one of the world's largest brothels [read, thousands of johns] in the village of Daulatdia, died of illness last week at the age of 65.

Sex work is legal in Bangladesh [convenient for all those johns], but Islamic leaders have previously refused to perform funeral prayers for workers. Instead, sex workers who die are usually buried in unmarked graves, without formal prayers, or dumped in rivers.

A number of people gathered at her grave to witness the historic moment.
