Some people adopt a persona on forums, to 'fit in'. Thankfully only happens on here to a very small degree, you know the kind of "I'd rather walk than drive a <insert non-VAG car> clowns. Would you really?? or anti-Police threads are another favourite of mine. Big heroics, not.
The tits on PHs are the ones shouting loudest trying to be noticed and gain some sort of acceptance from the elders by spouting what they think they want to hear. Funny things forums, they turn rational people into idiots and give idiots a voice.
