You said: I am not finding anything insightful from any political discussion online. Is it just me?

No it is not just you.

You asked: What do you think is the biggest reason for the current condition?

I believe the single-greatest contributor to the current condition is the way in which wholesale dehumanization of "the other" has been utterly normalized.

My opinion is that this type of Political Puritanism (seriously afflicting both sides of the political spectrum) is product of a "win-at-any-cost" mentality.
