I think this may be a more fundamental reason than tone for why the conversation here hasn't been as productive as it could have been. Your posts throughout have been easy to read as harsh criticism of Rust, which of course led to some arguments about whether or not the criticism was valid or the harshness warranted. But from the beginning, there have also been requests for you to use your perspective and insight to contribute to the effort to find solutions and help Rust succeed, rather than simply yelling from the sidelines, so to speak.
I would really like to emphasize to you that while constructive criticism is helpful and important, it's not helpful to simply complain while simultaneously doubling down on your status as an "outsider" who is unwilling to make a more constructive contribution.
So I would ask that if you really do want to see Rust succeed, pitch in! This doesn't necessarily mean pull requests or even writing your own RFCs; it does mean putting aside your "harshness" (because, as explained above, that's not how we do things in this community) and doing your best to learn and share insights.
Your last post in the first spin-off thread is a step in the right direction, and I hope you continue to contribute in that thread.
