Ray Bradbury expresses a strong sense of individuality and self-confidence in his taste and interests, particularly in unconventional themes like space travel, amusement parks, and gorillas. He dismisses any criticism directed at his preferences, indicating that he values his unique perspective over others' opinions. This illustrates his belief in the importance of staying true to oneself and one's passions.

By using the metaphor of "packing up his dinosaurs," Bradbury reinforces the idea that he does not tolerate negativity or judgment from others. Instead, he chooses to disengage from those who do not appreciate his artistic choices, signifying the freedom that comes with embracing one's own tastes and creative inclinations without concern for external validation.
