Edit 1: A good friend pointed out another angle of how the anti-vax campaign is insulting. It is a way to blame parents for their children having autism because they made the decision to vaccinate.
Edit 2: Oh how sexism lurks everywhere: According to a Maclean’s article on the subject, the reason they invited Jenny was because they are hoping to attract young women to the cause. Right, becuase young women are only interested in Pseudo-scientific bullshit, not real science. Come on Ottawa Cancer Foundation, seriously!? In reaching out to young women you insult them!? That does not seem like a good idea to me.
