Ad hominems generally work better when you don't make yourself look like an idiot in the process... you probably shouldn't be questioning what I know about parliamentary democracy when you clearly think the U.S. is one.
But your argument is also moronic for the referendum was conducted by an act of parliament. It wasn't just some random thing. The Conservative government promised they would hold a referendum on the EU, the proposed that referendum in parliament, and parliament approved it. So what will your argument be now? that a referendum is really only a survey to see what people say on a topic and with the results come no imperative to act?
