I agree, let's be open to new ideas and to revising our perspective. Humility is necessary if we know that our own knowledge is only based on the best information available.

That said, we shouldn't then count all our present knowledge as worthless and any and all kinds of information as equally valid and worthy of dissemination.

I do get your fear - censorship is a dangerous tool that is not always used responsibly. Yet abandoning any kind of social self-regulation in what information circulates publicly sounds a lot more dangerous.
