For me, the hoodie is a stereotype that Liverpool could do without. I get fed up with jokes and jibes about scouse scallies. I was born in Liverpool, as were my two sons - none of us enjoy these taunts. The girls are a great image, saying all that is best about Liverpool. I don't think they need the hoodie in the same image.
Given the name, rhart44 is close to rh1944 and that they're both from Southport and that they both have rh1944's fireworks, Liverpool and China photos I can only assume its our fuzzy little rh1944. I cannot account for his motives though.
