Sorry - do you doubt that it's an affidavit deposed by a real person, or do you doubt that the real deponent knows of what she speaks? And when you say "this sort of thing is expected", what is the "thing" to which you are referring?
I just can't find any reference to the actual affidavit, there is so called copies of it distributed by numerous not so trustworthy websites, but I can not find an official document to verify it's not just manufactured.
The sort of thing to be expected is the arguments against the government mandating something is normal, some truthful, some not so much.
