If I'm having a problem with a server and you commented "Former sysadmin was dumb and lazy, so they misconfigured it" (and you're correct) is that constructive?

I think we mostly all agree that we as a society caused the problem, but we can't go back and undo that. Constructive would be coming up with ways we can, given the past did take place, improve things going forward.

I disagree with your analogy. I'm pointing out specific mistakes in the former sysadmin's misconfiguration. And also that the misconfiguration can be rolled back.

We can vote for politicians that fund projects and facilities for general use and welfare. We can congregate more in the malls and community centers and bowling alleys (and churches too, if that's your style), that we still have. The loss of community isn't irreversible. Yet.
