I didn't ask it, Brundage did. And you're right, the money doesn't have to come from the government.Actually your point seems a herring.....as you ask "And is there any reason to believe that state legislators are going to appropriate sufficient money for that purpose? "
As weren't the majority of monuments actually raised by private groups then as well as even today? Certainly large numbers I have seen have plaques noting the efforts and donation from Union and Confederate veteran groups, then later heritage groups. There is nothing prohibiting current grass root efforts for monuments that I'm aware of.
Other then the current climate the anti memorial crowd themselves have engendered that may make public institutions less likely to accept a donated memorial in the future.
Just keep in mind: if the public feels that the commemorative landscape misrepresents the entire community's experience, they will not support it. I think you've written recently about the need for local support of pubic policy.
