There is a giant difference between a reabilitated child molester (who wouldn't be able to work with children regardless) and a former porn star (was she an actual porn star, or did she just act in porn?)
People consider porn to be such a depraved thing to be involved in, but honestly? It doesn't mean that the people involved in it are depraved or terrible people or unable to function in "normal" society. Are you going to try to take this poor woman's children from her next? Because, heaven forbid, she may try to force her loose morals on sexuality on them!
She is certainly responsible for being in porn, but so what? She's also responsible for leaving that industry, for attempting to make an honest living. Give her some credit.
