I blame Disney.
Hahahaha! You may be joking but I think you are correct. I’ve had the same thought for a long time. There have always been fairy tales using animals as analogs for people (Ugly Duckling, Aesops Fables, etc.), but Disney took it to a whole new level.
Disney has done more to make animals “human” than PETA. Moving pictures can put the mind in neutral and insert all kinds of pre-meditated messages.
I believe in part that it’s because our children are not taught critical thinking skills anymore. They miss the point entirely, and they are now grown and in charge of some things. Instead of taking a story like “Bambi” and applying it to their own behavior (be strong, be brave), they attribute human traits to the characters (dear are strong and brave).
I don’t believe this was Walt’s original motive. I truly believe he was a good man, and hoped to encourage children to learn good values, but after his death, the liberals who followed have figured out how to take this powerful tool for good and use it to promote their perverse agenda.
