My chapter dealt with this situation several times. I think it's best if a PNM brings it up first in early rounds like, "My sister is a member of ABC, but she isn't pressuring me to join there and wants me to find the chapter that's best for me." You're right about some sororities wanting to "steal" legacies, and you're right that some may write you off because your sister is an active member of ABC. When I came across this situation as a sister, I'd often make a note that you were a legacy of ABC but not "sold" on their chapter. Good luck!
