"If your ideas are any good, you’ll have to ram them down people’s throats.”
Translation of metaphor to 2,000 years ago:
Levant (Middle East), Bible verse Luke 17:21: "nor will people say, ‘Here it is,’ or ‘There it is,’ because the kingdom of God is in your midst."
In other words, people don't see what is in front of them. 2,000 year old Levant lesson / teaching to children.
