You admitted you were wrong so I reckon you can walk away with your dignity intact. It takes a big woman to admit she made a mistake. There's always going to be idiots who only read the OP before piling in and you know you can ignore them. So if I were you, I'd hide the thread and go and get yourself a large G&T.
Alternatively, change your name and join in on the bunfight, giving yourself a hard time.
Downside of option b) of course is that you will inevitably forget to change your name, someone will work out that you are one and the same, everyone will shriek troll and you will never be able to lift your head over the MN parapet again.
I'd stick with a) if I were you.
