conversely, there are many people who look down their nose at you if you do a factory job, and many people who admire or desire women who worked in porn/stripping.
That argument doesn't hold. No one ever lost custody or a subsequent job because they were formerly a factory worker. A former porn actress is treated by the bulk of society much the same way a sex offender is treated.
I wouldn't go as far as sex offender. It's true among prudish areas of society there is stigma (but then would you want to deal with those type of people anyway).
A lot of former porn actresses/dancers/strippers go on to marry wealthy businessmen, and many enjoyed their work. The same can't be said for factory workers.
