If you left it until after seeing punch and judy (Farage and Cameron) you probably dont realise that this referendum is about ending self government in the UK for all future generations. You are registered now so please remember that most people support an imaginary EU where everyone wants to hold hands and love each other. The EU is not like that, instead imagine the AfD and Austrian Freedom Party and Front National forming a coalition in 10 years time that runs the EU. The UK has about 8.5% of the votes and there are almost no vetoes. When this happens remind yourself that you were responsible for the UK being steamrollered into a nightmare.
It is not about easy travel or holding hands, it is about saving future generations from European political volatility. Remember, the Croatians were ethnically cleansing in the 1990s and genocide was happening in living memory. Remain means bringing such violent political events to the UK without any means to resist.
