Identity is, especially when you're a teenager, a fluid thing. You have lots of identities. And you can have an identity, you don't like it, because it's subverted in some way, or it's insecure, or it's inappropriate, you just delete it and get another one. The idea that you have an identity that's given to you by someone, the government or whatever, and you have to stick with that identity and use it in all places, that's absolutely wrong. Why would you want to really know who someone was on Facebook, unless you wanted to abuse them and harass them in some way? And it just doesn't work properly. And my fourth example is there are some cases where you really want to be - In case you're wondering, that's me at the G20 protest. I wasn't actually at the G20 protest, but I had a meeting at a bank on the day of the G20 protest, and I got an email from the bank saying please don't wear a suit, because it'll inflame the protesters. I look pretty good in a suit, frankly, so you can see why it would drive them into an anti-capitalist frenzy. (Laughter) So I thought, well, look. If I don't want to inflame the protesters, the obvious thing to do is go dressed as a protester. So I went dressed completely in black, you know, with a black balaclava, I had black gloves on, but I've taken them off to sign the visitor's book. (Laughter) I'm wearing black trousers, black boots, I'm dressed completely in black. I go into the bank at 10 o'clock, go, "Hi, I'm Dave Birch, I've got a 3 o'clock with so and so there." Sure. They sign me in. There's my visitor's badge. (Laughter)
