When it comes to cutting a legacy, it's my nationals policy that the member is called by the chapters rush advisor and told that her daughter/sister/etc will not be invited back. However, if the rushee cuts us, we don't have to do anything!
Which is really great, because I've heard of advisors that have broken down crying at the thought of having to make that call.
Carnation--I'm sure your daughters will be just fine. Let's face it, if a chapter does want to cut her based on her race, would you really want her there?
When you mentioned your daughters were adopted it made me think of one of my sisters. She's is Korean and was raised by a white family. But before I found that out I was shown a pic of her blue eyed blonde white sister. It took me forever to figure out that they weren't blood sisters at all!
I just thought to my self, "huh, I didn't realize she was mixed. It sure is odd that her sister doesn't look Asian at all though."
