This is an interesting discussion thread, and one where many commenters have no concept of what Girl Scouting is/does.
I get very tired of the argument that "girls already have Girl Scouts, it's just as good!" NO, it's not. Take it from a former scout, a leader, and a mother of a Girl Scout - their program has been utter garbage since their last overhaul about 6 years ago, and that's the way their HQ likes it. Girls spend up to 9 months of their year doing nothing but fixating on selling products for the Girl Scout machine (who makes billions off of the girls labor, then acts like they're too broke to invest in any local programming for the girls). As a leader, make no mistake, GS wants product sales to be all life consuming, and it's become one step shy of a pyramid scheme like Pampered Chef. GS are closing camps left and right, but it's not because girls don't want to camp, as some have suggested on here (my own daughter camps in our private woods every chance she's allowed). Girl in Girl Scouts aren't camping because families can't afford to participate when the financial aid rates that GS offers are still twice the cost of a full-priced week at BS camp - and girls don't even get to earn any badges or awards at most camps!
Not to mention the lack of accountability for the girls and lack of respect from their parents. You could never have ranks in GS because parents would stomp their feet and cry out that it's not fair how their daughter does no work, never shows up, and doesn't get the same awards as everyone else. I can't tell you how many times parents have called the council on me to complain about just that problem! You may see problem parents in Boy Scouts too, I have no doubt there, but you have no idea how much more respectful women tend to be towards male leaders over female ones. And, the entire reason I became a leader is because the first troop my daughter joined had tons of money vanish (in the 5-digit range) and when I went with others to complain to council, they looked at us and said "after we get our money, it's none of our business what happens to the girl's portion!" It's a ludicrisly bad program, with staff that has no clue or care about the girls they're supposedly working for, and it's been re-tooled to only cater to kids in metropolitan areas. GS doesn't even pretend to care about anyone else, which is likely why GS keeps complaining about hemorraging members, because it's largely an arts and crafts mini-daycare these days. They do not truly develop leadership programs, and most girls have to be Juliettes (ie non-troop members) by the time they're in 6th grade, because there is so little interest in the program as girls get older/more unhappy with their lack of options. So, in short, Girl Scouts is NOT the same as Boy Scouts!
And, to users like Back Pack, who think Venturing is just the same as Boy Scouts, again, you are so very mistaken. First, a female has to be 14 to join Venturing, whereas a Boy Scout can technically start at 10 1/2. So Venturing is only open to girls who are roughly high school aged, meanwhile younger girls have a great, if not greater, interest in scouting too. Second, you cannot earn merit badges or Boy Scout rank in Venturing, which, whether you want to admit it or not, are very respected things to earn - to the point that the military will give you an automatic promotion if you have Eagle Rank. Third, I live in a highly active state for BSA, you can't go down the block without tripping over a troop, and, yet, with all that support for scouting here, the Venturing units exist on paper only. They don't meet, they don't have activities, and every Crew leader I've met tells me the same thing - they're ready and willing to have their Crew be amazing, but there are too many competitors for time, money, etc to get the high school aged kids active.
So, to say the GS/Venturing are the same quality as the Boy Scout program is like going into a hotel and being given the option to have a room with a bed, or a room with a pile of rocks. Yes, I'm sure there are some areas where GS and Venturing are amazing and active and well executed, but that is not the case for many youth. And no girl who would enjoy the BS program would mind being called a BOY Scout. Just like women don't get offended if they join the military and get called a soldier, even though that always implies a male (just ask my mother the veteran, who can't wear a veteran hat without being asked if her husband/father served!). When you love a program and you believe in what you're working towards, being called a Boy is not the issue they're concerned with.
