So men should never argue with women because we can't get away with hitting them back? That's a bunch of fuckin bullshit.
You don't have to hit a girl if they slap you, you know. But if she slaps you, she can't bitch about you slapping her back, same as if you call someone a cunt you can't bitch about getting slapped for it. Doesn't justify it though. If someone called you a cunt to your face and you hit him for it, it'd be understandable, but it'd still be a dick move.
Calling someone a cunt isn't an arguement. It's an insult. And if you insult someone, then you've gotta expect someone to go off at you for it and, more to the point, not bitch about it on a fucking message board.
If she's so much of a cunt, just take the fucking higher ground and don't say anything to her. If you think she's so much of a cunt, what's telling her gonna achieve other than making you think you're cool because you called her a cunt. If she's a cunt, she's obviously not gonna give a fuck and even if she did then you don't give a fuck about her life so any change aint gonna matter unless you're extremely petty.
My guess is you still fancy her, she doesn't wanna know so you acted like a dick, got punked out and are now trying to get some sort of justification for your actions from a load of other rejected blokes.
