"... Girl Scouts of Colorado welcomes her as a Girl Scout."
But what if a child is presented as a boy who has a strong identification with things that are traditionally female? Here's Bobby Montoya, whose mother tried to get him into the Girl Scouts, but didn't claim he was female:
My problem with this is that the argument that he belongs in the Girl Scouts is premised on stereotyping girls. I think the better argument for kids like Bobby is: Let children choose their own toys, hairstyles, clothes and don't make a big deal about whether he or she has chosen things that are more often chosen by members of the opposite sex. Emphasize individual freedom!
Bobby's family put him in a situation where he was excluded because — as the troop leader allegedly put it — he has "boy parts." He has a real physical difference from the girls, and he was classified based on that, not his personal preferences and interests. Now, he's focused on genitalia-based limitations, as if his natural body parts are his problem!
AND: When is it appropriate to make your child a gender celebrity?
