Eh, basically... I don't want to seem insensitive here; Nabu, I've no doubt what you did was the right thing, and the guy you did it to was a complete fuck who fully deserved it. I hope that's clear. But I don't like the posting of a war-wound picture, with subsequent macho 'I'm fine, you should have seen what I did to the other guy' stuff. It's not so much that even, it's the fawning here. I'll explain my ridiculous viewpoint:
Recently, I was involved in a similar altercation, which (predictably, all fights with me tend to go this way) involved me, Mr Manly Man, coming to the aid of a woman being harassed by a guy. I'd like to say I left the fight with a Nabu style scar with the other guy in pieces, but I've got a black eye, gashed arm/chest/face and about five broken fingers courtesy of three grown men (his mates were around the corner) and a flick-knife. (Please don't offer any sympathies, what I did was stupid and not to be encouraged.)
If I'd won, I'd doubtlessly be proud (and in a way I did, the woman was fine which was my original objective), but being on the losing side is horrible. I was humiliated and put in great physical pain, and if the fight had gone the other way for you, Nabu, it would be horrible for us all. It's easy for people to say 'Wow, what a sexy scar' 'Nabu takes names and kicks ass with impunity', but I may be left with some very, very ugly scars, and violence is an ugly, ugly thing. I fuck*ng hate seeing it glorified in this way.
And fuck, now I sound bitter that Nabu won his fight and I didn't. I'm really glad you're (relatively) fine Nabu, I like you a lot and don't question your judgement on what you did, and the fact you're okay is far more important than my stupid feelings on you posting a picture of yourself. Don't get into another fight anytime soon, though.
