I completely agree. 2% of the population deciding something of this magnitude is ridiculous.
If the UK had voted to leave, with only a 2% margin, would you have complained that it was to little to determine something of this magnitude and called it ridiculous?
Regardless of the outcome, the EU needs to re-evaluate how it operates and if it needs to change drastically. I'm a fan of the idea of an EU, but in it's current form it's an almost unmitigated disaster and a role model for people wanting to circumvent democracy.
