You’re absolutely right about single issues being absorbed, the most prevalent being gun rights and abortion in the u.s… I think I lean much more on the side of education and civic engagement you mentioned. Not easy to shove that down anybody’s throat. The moment you try to introduce a larger extent of that you’ll get the “brainwashing our kids” crowd crying fowl, even though they’re right. My solutions to these problems aren’t well received or practical given the current state. While I understand your objections and am willing to throw caution to the wind I don’t think a change to PR will really be of consequence.
Edit: I came back to this because I realized this sounded too defeatist. Certainly PR or something similar is the next best step. Nothing we do will happen quickly so the most important thing always is to keep moving.
Just for that I won’t be reading this post.
