He doesn’t need to come up with a comprehensive solution. I imagine he could have confidence in his perspective but not so much about how to resolve it. He characterized the situation in a way that seems callous but aligned with reality. You don’t have to cover all the basis when commenting.

If you agree with the characterization you can debate potential solutions. Seems more productive than doubting the stance the person who is bringing a potentially useful perspective. Generally it’s necessary to have a good grasp on reality when trying to solve an issue. Id rather see it as the first step towards a solution.
