A good start would be to reinforce freedom of speech, especially in academic circles and on social media sites. Anything short of direct incitement to violence needs to be tolerated. Direct incitement to violence is already prosecutable, and therefore does not require media censorship.

Also, MSM organization need to stop forcing top-down philosophical and political positions viewpoint onto their journalists and other contributors.

Edit: Apologies and thanks to @ViviMack, who, I just noticed, made the same points earlier.

Okay - so maybe those who said the subject is too broad are correct. So let’s narrow. The political system is broken. By that I mean that congress spends almost all its time either pointing fingers or raising money. On every issue each side retreats to their corners and refuses to compromise. How do we get back to accomplishing meaningful legislation for the country? Better?

Solutions to which problems? The system is broken in large part because we have asked / allowed government to take roles not given in the Constitution.

I think a Convention of the States is a good start.

[conventionofstates.com]

"Article V of the United States Constitution, restricted to proposing amendments that will impose fiscal restraints on the federal government, limit its power and jurisdiction, and impose term limits on its officials and members of Congress."

They currently have 15 of the required 34 states signed on
7 states have legislation passed in one chamber
12 have active legislation.

We need to reclaim our power from Washington.

Start a discussion that is s little less broadstroke of society. Like others sat, stop looking at it as "us" against "them"(team sports bullshit) and start looking at people individually.

None of these labels we use for others in a political spectrum mean anything. They really don't. What does left mean? What does right mean? What compass heading are we facing at the time?

If you are looking north and say left and i am looking south and say right, are we not talking about west? Or maybe i would have ment correct? Or maybe our personal orientations to self are fucking up our ability to communicate.

Ooh, o feel a rabbithole appraching...tatafornow

What is the problem you're tying to solve? In the current polarized culture, conversation is impeded by ideological dogma. Maybe it would be sensible to first discuss how to solve the gridlock complicating our conversations. Does the culture war have to have some definitive outcome before we can start solving social policy issues together? It seems hearing the other side has become pretty tough, so how do we create safety and open the channels of communication with people who think you're the 'them'? But, this is your post. What is it specifically you want to talk about?

Reinstate Civics and Government in the school system as a required course. Preferably once in 6th, once in 9th and once in 12th Grades as “Full Semester” courses (at least) ... similarly, History, specifically US History should be reinstated.
I know that is not any of the three you specifically mentioned but if people ... young adults ... were exposed to this, I don’t believe the Left would have anywhere near the traction or following it presently has.
