Liam if you would like to debate scripture and history, I'm up for it, as I'm well versed in both,
Firstly, doing OnlyFans is in no way comparable to first century prostitution.
Without any form of social security or government support, abandoned wives and their children (which was apparently common in Israel) had no options to support themselves, unless they had other family to return to. And unlike the movies, most people lived day to day, just above the poverty line. So inviting your sister and her kids back into your family long term, would have been a big ask. Recall too, first century had a virtually non-existent technical and middle class, which highly stratified the distribution of wealth. Which meant, most had little in reserve.
On the other hand, women today have a lot more choices and support than back then. Living in a crisis center must not be good at all, but even that is more than what was available back in Biblical times.
Thus its obvious these girls make OnlyFans; a lifestyle choice.
Scripturally Liam, of course we can judge people. We CAN judge them when they CONTINUE in a sinful course. The Bible is plain in this point. However if a person repents and stops disrespecting God's mercy, then of course, we must view them as Jesus did. Otherwise the whole concept of sin, just doesn't work.
The example you used in John chapter 8 actually supports my argument, not yours. In that the woman in question clearly displayed a contrite and repentant attitude a Jesus's feet. She was also a adulteress not a prostitute who was in the 'business'. Which is a far cry from the shameless OnlyFans girls who publicly promote their 'alternate lifestyle' ... unlike street prostitutes who work in the shadows of society.
People can make wrong choices in life and end up in a bad place ... but like the prodigal son in Luke 15, a person must be willing stop what they doing, to receive forgiveness and a new start.
