Added Sep 26 2019: I'm not going to do an analysis or summary of these responses – but I and others think it would be interesting to do so. If you'd like to do so, I'd welcome that and will link your summary/analysis in the top of this post here. All the data is accessible in the Google Spreadsheet below.

Let's start with a test: Do you have any opinions that you would be reluctant to express in front of a group of your peers?
If the answer is no, you might want to stop and think about that. If everything you believe is something you're supposed to believe, could that possibly be a coincidence? Odds are it isn't. Odds are you just think what you're told.
Why this is a valuable exercise
Some would ask, why would one want to do this? Why deliberately go poking around among nasty, disreputable ideas? Why look under rocks?
I do it, first of all, for the same reason I did look under rocks as a kid: plain curiosity. And I'm especially curious about anything that's forbidden. Let me see and decide for myself.
Second, I do it because I don't like the idea of being mistaken. If, like other eras, we believe things that will later seem ridiculous, I want to know what they are so that I, at least, can avoid believing them.
Third, I do it because it's good for the brain. To do good work you need a brain that can go anywhere. And you especially need a brain that's in the habit of going where it's not supposed to.
Great work tends to grow out of ideas that others have overlooked, and no idea is so overlooked as one that's unthinkable. Natural selection, for example. It's so simple. Why didn't anyone think of it before? Well, that is all too obvious. Darwin himself was careful to tiptoe around the implications of his theory. He wanted to spend his time thinking about biology, not arguing with people who accused him of being an atheist.
Thanks to Khorton for the suggestion to do it as a Google form.
For what it's worth, if I could choose between this form existing or not existing, I would prefer that it exists. But we can also try to think about something in-between. Like:
(1) We agree in advance that there will be some clean-up of the form before release. We clarify what this means, I suppose that we will want to say that offensive or ad hominem content will be removed. Maybe we propose a list of made-up examples to explain what we want to be removed. This will be subject to some debate, but we can figure out something reasonable.
(2) We collect all the answers without disclosing them.
(3) We ask for a pool of people to volunteer for cleaning up the form.
(4) We select a small subset of these volunteers at random and they do the job. They check on each other for the cleaning, and then release the cleaned-up form.
I suppose that the simple fact of having this structure in place will already essentially clean up the form, whatever we mean by that.
I also think the form should exist. I would agree that attacks on individuals should be removed (with a comment left explaining why). I'm uneasy about screening the comments more than that, as then people may not trust that no bias has come in. For negative comments about organisations, perhaps people could be encouraged to briefly explain their thoughts and link to evidence. I would hope that people reading the comments would know to take criticism of organisations with no evidence given with a very big pinch of salt, since there will be people around with gripes due to rejected applications etc.
