This, I think, captures the problem quite well; "please don't do this, all it does is create drama!"

Maybe so, but the best way to end up with well-intentioned people absolutely hating each other is to never allow the airing of grievances.

I'm hugely in favour of kind, empathic, and thoughtful communication, and I don't like the "people yelling at each other"-type of projects to the point I simply don't participate. But part of that is also accepting that sometimes people express themselves in less-than-ideal ways, and allowing for the fact that sometimes conflicts happen, and that some amount of yelling and drama is necessarily for a healthy community (or indeed, most relationships between people) because we're all flawed and emotional beings. Rust took a good idea and pushed it to the extreme, which rarely works out well.
