I find it really amusing that some in the Remain camp are complaining that this was too close a vote for such an important topic.
Might I remind everyone that this was a slightly larger win, percentage-wise, than Obama's "landslide" re-election victory over Romney. (Maybe we should have a do-over on that one too.) If this had been a 50.5% to 49.5% Remain victory then this would have been considered Settled Once And For All.
If you cared so damn much you should have got your ass out and voted in the first place.
If you really want to prove right all of the people who are angry that they're not being listened to and that the government doesn't care what they have to say, then ignore this vote. The reason we don't have armed revolts is because people have the ballot box. Eventually you'll get what you deserve if you take that away from them.
