Final answer:
False, although the Shakers' practice of celibacy led to their numerical decline, their design aesthetics have had a lasting, influential impact.
Step-by-step explanation:
The question 'T or F. Shakerism is a sterilizing meme' can be considered false if we understand a 'sterilizing meme' as an idea or practice that limits or reduces the spread of itself. The Shakers are a Christian sect formally known as the United Society of Believers in Christ's Second Appearing. They believed in creating a heaven on Earth and held some progressive tenets such as gender and racial equality, communal living, and celibacy. While their celibate lifestyle did contribute to the numerical decline of their community, the meme of Shaker design, which emphasizes simplicity, functionality, and craftsmanship, has had a lasting impact and continues to influence aesthetics globally.
