There is nothing wrong with some people working on a regional or global fix while others work on a local one. The important thing is that they’re working for it.
But this ignores the humanity of people on the other side of the issue--people who may have legitimate moral and philosophical questions about very difficult and complex issues.
It does seem that acting locally, within the realm of actual human relationships rather than alienating impositions of authority, would likely result in much greater good in the long term.
Like diplomacy with regimes you find reprehensible may still be preferable to war.
There are many progressives that can't even manage that.
I don’t think “global” fixes ever work well. In practice throwing out everything and starting from scratch just makes the overall situation worse.
Sustainable, lasting progress happens incrementally.
