Seriously!
The point of “Read another book” is “Stop mentioning a popular children’s book series to make oversimplified analogies to complex political issues” because most often, people were like “This political side I don’t like is just like the Death Eaters and Voldemort and this side that I agree with is like Dumbledore’s Army!”
But drawing a comparison with something innocuous like “I’m going to be a better person than my father was,” “Oh, just like this character from this book series I really like!” that’s fine! That’s different!
