American activist David Thibodeau survived the Waco Siege, which happened in the Waco area of Texas in 1993. His wish to engage with regular Americans who might not be aware of or curious about the specifics of the event is reflected in the quote you cited.
The goal of Thibodeau's writings is to close the gap between people who are directly impacted by important events and those who might ignore them out of ignorance or disinterest. By referring to typical American families as "Mr. Joneses" and "Mrs. Smiths," he hopes to connect with regular people and draw their attention to issues that may seem disconnected from their everyday lives.
Consider a huge ocean, with each wave standing for a person's perception of current affairs. Thibodeau is comparable to a sailor who aims to land on every wave, no matter how big or prominent. He works to ensure that his message reaches and influences even the smallest waves, which stand for common people who might not consider complicated issues.
David Thibodeau highlights in this quotation the significance of educating people outside of those who are directly involved or have a strong interest in particular issues about important events and their effects on society as a whole. His objective is to make these gatherings meaningful to everyone so that everyone feels informed and connected.
