Stability of government is a perfectly legitimate defence of a first-past-the-post system, but that carries an inevitable democratic deficit - you're arguing for the benefits of constraining the choices of the electorate.

I'm somewhat sympathetic to that argument, but it places a far greater onus of responsibility on our dominant parties. If our electoral system prevents a diverse range of parties in parliament, then those parties have a duty to represent the diversity of the electorate.

In the case of the EU referendum, they have a duty to represent the interests of both the 52% and the 48%. Totally ignoring almost-but-not-quite half of the electorate is just mob rule dressed up as democracy.
