Tons of movie villains from the 80s were based on Trump and America still elected him president. Movies have had environmentalist messages for several decades, and humanity is still destroying nature.

People who think art will make a huge difference in altering people's perception of the real world are idiots. Preachy messages only get in the way of good storytelling.

Unfortunately many artists want to feel like they're "making a difference" and aren't satisfied with bringing entertainment into people's lives alone.
