>Mainline Disney movies these days are, on average, more politically bland than the beloved “renaissance” classics.

What exactly was political in the Disney “renaissance” classics?

>The latter tended to be extremely liberal, even by historical standards—some of them shocking to watch, now.

Nothing wrong with being liberal. The issue is with the flavor and definition of liberalism you choose as the benchmark. People are NOT OK with gender swaps, race swaps, and forced LGBTQ inserst in ther entertainment masquerading as "liberalism" when it's propaganda inserted by activists designed to "own the (chuds)conservatives".

The liberalism of the 1990's Disney “renaissance” classics would be considered conservative and even bigoted by today's modern definition of liberalism that activists have co-opted.
