Pending those answers, so what.
Here's my guess - the District put out general offers to participate in the reading program. Grey's manager was contacted by a Democrat political operative who had a brainstorm about yet another way to infiltrate society, and told to have Grey volunteer. She does, and the Districts own "zero tolerance for hate" meme so paralyzed every single administrator and teacher involved with the program that even if they wanted to exclude her (and most literally couldn't see any reason not to), they simply did not have the administrative tools to even object without endangering their careers. So, lacking any method to stop her, Grey was included in the program.
And as for why this is important, it is a perfect example of how liberals do everything - by changing all the rules so that no one can do anything, and no one is responsible.
And the most dangerous exploiters of this insitutionalized craven cowardice are the Muslims. Sharia law, if it is ever insituted in this country, will not establish itself through winning any legal fights - but because all legal barriers to it were previously stripped away by liberals.
Just a guess, but she may have used her real name and not her stage name. So, Sasha Grey may not have been on the list.
