Inspector Gadgets blogentry is interesting -- like many he is so disgusted by the entire thing that he just fails to see why people are paying Moat this kind of tribute. Here is my comment:
I'm amazed you don't understand that this hero worship of Moat actually is the last remnants of an instinct for decent principles his fans have.
What (distorted shades of) values did he demonstrate to his audience (not to us!)?
1) He didn't just discard his ex, he cared enough to be seriously upset(if he didn't he'd not have shot her and just moved on to the next woman, as there was a queue of 'ladies' waiting for him anyway). Most men of his 'status' (and stature) nowadays wouldn't care about loving (for strange values thereof) a women at all but change them like underpants.
Women appreciate that kind of 'romantic loyalty' nowadays, especially since the only steady men on offer (if available at all) are feminised wimps. (and of course, all those 'good girls' would not have set Moat and the new guy up for her private Circus Maximus game either, honest guv)
2) Moat took care of the guy who 'stole' his girl and lived in his house (You had that spot on. in fact this entire thing was an Anglo-Saxon honour killing). This does have a lot of appeal, especially to the hen-pecked and cuckolded males of today.
3) He took on 'The Man'. Chavs, just like Lefties have a penchant for this probably from watching too many movies or so... the dream of David vs Goliath lives on here.
4) He did what he said he would -- he was a man of his word. This is a rare thing nowadays.
In other words, in todays' world of neutered plastic people, Moat tried hard to be a 'real man'(tm), and whilst it was a caricature thereof, it still comes closer to 'the dream' than reality -- he was a real life 'Conan the Barbarian'.
The hero worship of Moat is a strange protest at modern morals more than it is a tribute.
As for the tale about baseball bat to spine... look, if he whacked her with this in any meaningful way, she'd be in a wheelchair(...). As for the rest of her story I refer the honourable Inspector to the tattoo she wears and the fact that they appeared to have a BDSM relationship without safeword or sanity. I'm certain that *everything* she claims is true, just not in the way we think it is... ;-D
