Ahhh. Truth be known, it was probably the derailleur hanger that was bent and can be fixed for merely the cost of a five minutes work. Having said that, I can see where folders could be difficult with gears. I've often wondered about a fixed gear folder, I reckon it'd fix a lot of sins. Of course, bypassing the folder in the first place also works, which is why I spent so much getting a custom made tow bar fitted to my MG ZR160 ... for the bike rack.
