The Redskins have come under growing pressure to change their name after claims that it is offensive to Native Americans, although the franchise has consistently refuted the accusations.
Birch does not believe that the name constitutes a racial slur, but also stressed that it was not a matter of deciding simply whether it is offensive or not.
"The team name is not a slur. The team name is the team name as it has been for 80-plus years," Birch told ESPN.
"And what we need to do is get beyond sort of understanding this as a point-blank situation and understand it more as a variety of perspectives that all need to be addressed, that all need to be given some weight, so that at the end of it we can come to some understanding that is appropriate and reflects the opinions of all.
"I think that is part of the issue with the question is that it is constantly being sort of put into a point-blank, yes-or-no, yes-or-no kind of context when that's not the reality of the situation that we're dealing with."
