“A proposal to revise or eliminate an existing personal commemorative name will usually be disapproved unless the proponent presents a compelling justification.”
There is no such compelling justification to change the McCarran name; only some cherry-picked politically correct excuses.
“A proposal to commemorate an individual should include evidence of local support for the proposed name and its application. Such evidence may be in the form of letters from the appropriate governing authorities and local residents, as well as, where appropriate, from historical societies, service organizations, etc.”
“The staff also encourages proponents to solicit support from neighbors, property owners, local businesses, and others who are familiar with the feature and the name proposal. This process may occasionally generate a counterproposal to the original proposal.”
