Feif Un: You are a boi
intellegent: you are a Girl
You will not agree on the issue of Taava. You are just too different (can it be any more obvious?)
(somewhat serious post)
Teenager’s point is if there is a Mutar way for guys and girls to Hang, they will (possibly) not do so in the back seats of cars or skating rinks (which leads to Baaaad “stuff”).
The worry is if it has a “Hashgacha”, those who would not have anything to do with the opposite gender may think its OK. I would go for supervised, following Halacha, but no “hashgacha”. That way there is “plausable deniability”. 🙂
Also, no-one would fundraise for the program, so you would have to find a sponsor who understands what is going on and is willing to pay for it (also not easy).
Good luck.
