I think the key issue here that lulubel has is fear of stealth camping, and whether it is worse for a woman. Fear is mainly just that - fear, with no basis in reality. But as a bloke who has stealth camped 3 or 4 times, I know how spooky it can be. The key is not to be spotted going into your camping spot, and to choose carefully. My plans for future tours will include much more of it though.
In reality, I guess women are seen as more vulnerable by men and a tiny minority of men will take advantage of that vulnerability. Would not stop me as a hefty bloke being scared as hell if I heard someone coming up to my tent in the middle of the night though.
Not sure any of the above helps.....? However of the people I have read about on Crazy Guy on a Bike, the number that have had any real problems/aggression/assault/theft etc whilst stealth camping is tiny.
