Eh only 43% of the vote though. It's just FPTP that cause the majority in the house of commons. It wasn't exactly a binding win for Brexit considering the parties pushing for either remaining or another referendum won more votes overall. Plus a big part of it was a vote against Corbyn, rather than a vote for Brexit.
General elections are too general to be used as justification for a single policy IMO.
Oh it's totally normal for someone to shoot themselves15 times with a gun that holds 11 bullets. They probably reloaded halfway through.
