21:40 I'm sorry...but WHAT?! 😮 "You won't make the dumb talk or the blind see"?! I understand that using that word in this context is technically acceptable in regards to its definition, but could you not have chosen anything else to use as an example?! Even your slide says something that's far more appropriate, way less offensive, and completely acceptable. I really hope you will consider editing the audio and using a different example ❤
