I can guarentee that no one here is a saint. Not a single one.
If Sasha Grey wants to volunteer in public schools, where she will be instilling a love of reading in the children who need it most, then I will applaud her for it. Her career as an adult actress is entirely irrelevant to the good work that she is doing.
So if you have some sort of problem with an OMG!porn star interacting with children in a safe and educational manner, take a moment to consider your own shortcomings: There is something in each of our lives, both past and present, that isn’t appropriate to share with children. It’s a part of being an adult. If you’re going to stop her from doing volunteer work, then perhaps I should start judging you based upon your old college days of alcohol poisoning and the wireless internet you’re stealing from your neighbor.
