@JGoldman10,
The Knights of Columbus are a Catholic fraternal organization.
According to Wikipedia,
"It was named in honor of the explorer Christopher Columbus. Originally serving as a mutual benefit society to working-class and immigrant Catholics in the United States, it developed into a fraternal benefit society dedicated to providing charitable services, including war and disaster relief, actively defending Catholicism in various nations, and promoting Catholic education."
Disclosure: I did receive an award from the Knights of Columbus for my years of Alter Service in church.
People started to look critically at Columbus and his life in recent years, at least starting in the mid 2000s.
