Amanda Peet's Apology: Sincere or Damage Control?

Actress and mama Amanda Peet published an apology in Cookie for calling parents who don’t vaccinate their kids “parasites” during an interview. The mother of 18-month-old Frances said:

I believe in my heart that my use of the word "parasites" was mean and divisive; I completely understand why it offended some parents, and in particular, parents of children with autism who feel that vaccines caused their illness. For this I am truly sorry.

What are your thoughts on her apology?
