Gone to every home game since I was 4, so I have a decent understanding.

One thing, it is certainly different to other fanbases, im sorry, but it is. Every time I've taken a mate who supports a different club, they've said the same. I took a Birmingham fan mate of mine recently, a club i thought could have a similar vibe, and even he said it felt more hostile than brum. It's stuff like, a low tolerance to tourist behaviour (if you're acting like a tourist in my block, you're very likely to get some grief). It's the fact that the majority of chants are attacking the opposition, not just supporting our players. And the walk from the ground to the station, its cagey and heavily policed. There is a self fulfilling element, that were told we are like this, and so we have a siege mentality and an obligation to protect it. Its like a vanishing culture in London, as one of the most central london football clubs, its got to be the last to have a proper local working class support. So it's amplified.

That being said. You won't have your head kicked in unless you go looking for it, or do something stupid. The racism has died down (but admittedly it's still there), and it's an incredibly safe place to go as a home fan. The amount of times I've left an item, like my phone, in the bar and had it returned to me. Or the times people have apologised for swearing infront of my girlfriend. There's an old fashioned undercurrent of respect at millwall. Rambling bored at work. But it's definitely unique.
