Argument 2 feels closer to what I believe to be an honest and ethical response to the 30 years of history between the crash of 1987 and the installation of "Fearless Girl."
One could argue that the values espoused by the Charging Bull ultimately led to the financial collapse of the 2000s. As such, Argument 2 is stronger as it is better to stand by a message of a young fearless girl standing up to adversity than stand by the reckless reaction of a charging bull that led to a period of deregulation and reckless capitalism.
