coarsened

The national discourse has coarsened, partisan divisions have sharpened and become more entrenched, and the standards for candidate behaviour have eroded.

The angry and often binary arguments of the Brexit years at Westminster - on all sides - coarsened the tenor and tone of political debate.

To say our politics have coarsened over the past few decades is like noting that temperatures drop and daylight shortens as we settle into autumn.
