Magdalene women slaved for a Church obsessed with sexuality

Given that these girls and women lived lives (in some cases, whole lives) of brutality, drudgery, and shame, stripped of all basic human rights — even their names — while working for free for the financial benefit of those Catholic institutions, I think my meaning could hardly be clearer.
Ms Griffin asks why families sent their daughters to Magdalene laundries and why, at the end of their wasted lives, those families did not claim their bodies. Ms Griffin urges that I answer her with “honesty and common sense” and without resorting to clichés. I’ll do my best with the first two, but the last may present me with a difficulty. Is it a cliché to say that girls and women were sent to the laundries for the sin of having had unsanctioned (and not always consensual) sex?
