The illusory nature of moral progress

The illusoriness of the notion of moral progress.
From the 60s onward we have what is deemed to be moral progress 
 

by advancing the goals of racial and sexual emancipation 

  – women, people of colour, LGBT people et al

The yang to this ying is the populist movement of Trump/Brexit

who assert all 'this'  was no more than a niche distraction, a gimmicky leftist aberration, a game as if the centuries’-long push toward enfranchisement, civil rights, equal pay, and reproductive autonomy, and against domestic, sexual, and police violence were a game.

Our moral horizon moves with us as we move, and never do we draw nearer to the far-off moral perfection line where the black waves and the azure meet.
