Doesn't matter what they say or (barring extremes) what they do. Someone can walk up to you in the street and say your mother is a slag and they are going to rape your sister and your a sissy twat that can do fuck all about it. If you hit them, it's ABH ( probably with intent) if you hit them too hard, it's GBH. For both of these 'crimes' you are looking at a prison sentence. You can offer provocation as a defence but if you've hit first, you are in serious trouble. Why has the law totally taken away your right to slap someone?
The worst offenders are the middle class pricks who have no idea, through lack of experience, that anyone could ever possibly ever actually smack them in the fucking mouth. They really believe they can say what they like. My neighbour is a prime example and he is sailing well close to the edge. But what kind of a society is it where your only legal recourse is to spend £1000s trying to prove slander, harassment or whatever?
I have to listen to the twat and keep my hands in my pockets. Because if I do what normal human nature dictates and batter the ****, I'm the one who is going to get convicted, fined and probably lose my job aswell. It isn't right!
