I think it has to happen locally. Ranked choice voting (or similar) needs to be pushed through. Then, school boards, city/county councils and state elections.
People need to recognize and relate to new parties. National elections are not the way to do it (fuck you Stein and the American Green Party).
The right wing has been pushing the Democratic Party to the right by making the Republicans more conservative/fascist. This pulls the Overton window to the right and the Democrats with it.
Socialism in the Democratic Party is the natural reaction to this pull. While welcome, the real solution is to do away with the two party system. Otherwise, it’s just a see-saw forever swinging back and forth.
I think the point, and usefulness, of this question is to get the many different kinds of answers. As you point out, it’s a nuanced social issue. It would help some people to hear all of the perspectives so they can adjust their behavior appropriately.
“Stupid” definitely falls on the nurture side of “nature vs. nurture.” So, it’s not eugenics to want stupid people out of the gene pool. They will nurture stupidity into the next generation not pass on a gene. It is a failure of a society’s education system. The children of stupid people could be raised not-stupid.
I’d like to see Ireland use the green field with harp flag. I get the symbolism of the tricolor but it’d be nice to move past the Catholics vs Protestants and leave religion out of it. Maybe, if re-unification happens.
Intentional Incompetence would also work.
