There are a lot of myths and misconceptions about self defence and the law. One of the biggest myths is that some methods of self defence are legal and others aren’t. This is complete and utter rubbish. There is no such thing as a legal or illegal technique, self defence is always relative to the situation.
If a girl cuts her boyfriend’s dick off with a pair of scissors in his sleep, it might not sound like self defence, and it wouldn’t be if she did it because he forgot to put the toliet seat down, never lets her have the remote, couldn’t get it up, or cheated on her with the slut down the road; but it would be if she cut off because he had just raped her and she was lying besides him on the bed, held captive in her own home for fear of waking him.
Hitting a man below the belt and biting might both be against the Marquis of Queensbury rules, but if a girl’s unarmed and she’s attacked by a man – sod the English aristocracy – one of the few physical advantages she has over him is that no matter how big or strong he is, or how magnificent what swings between his legs is – he’ll scream like a 10-year old girl if she hits him or bites him hard enough there. She might not be able to kick or knee a man in the groin because his defensive reflexes are too good but she can easily grab hold of his balls, and it doesn’t take much to rupture his testicles or in extreme circumstances, if she feels she has no choice, she can fall to her knees and bite them off. As long as her actions were defensive and proportionate to the risk she faced she has acted in self defence.
In Italy, a girl recently thwarted a rapist by biting his dick. She wasn’t prosecuted, she was treated as a heroine, and so she should have been because she is. Castration might sound like something only a man-hating, vengeful feminist would do, and I’d agree that it’s a horrific thing to do to a man but if a man gropes a girl’s breasts and slides his hand up her skirt and instead of letting him do what he wants, she manages to emasculate him… well done her!
