Dismissing Linnaeus work is insulting all biologists in this planet in a single move. The guys in the Gustavus Adolphus College are sending a clear message, and the message says that they are complete morons that replaced science with ideology.
Everything that is alive currently is either named by Linnaeus itself or named after the work of Linnaeus. We call ourselves Homo sapiens because Linnaeus created that name.
Is a private place and they can replace every bust with pig heads for fun, or name it anyway they please, but I would never, ever, go to a place that did this to one of the most relevant scientists in the history. Is simply repugnant.
