Actually there never really was. She's always closed them on all of the videos from the get-go.
And getting trolled on TY comments is no excuse for totally closing up from all criticism.
This is a ridiculous point. She's done her part. She no longer is required to engage with anyone on the topic, if she doesn't want to.
When you write an essay, your job is done. When you release a documentary, your job is done. When you create a poem, or a painting, or even a joke, your job is done. It's then up to others to discuss the meaning and merits, which they can do on their own time, in their own space. If you, as the creator, also want to listen or engage, fine. But, in this case, Anita's job is done.
She's not silencing discussion. And you're not really asking for it. You're saying she has to keep talking, in a forum of your choosing, until you and her other critics are personally satisfied. Which will never happen.
Because the lack of discussion is not her critics' real problem with her. If anything, the gross threats she's received have shown that what many of her critics really want is for her to shut up.
