EU referendum, brexit and the aftermath

I'm just picking up on May's surprisingly clear words yesterday, and the stark negative implications for each "alternative solution" that can be delivered.

So a second referendum "risks dividing the country again, when as a House we should be striving to bring it back together." Is that it? Is that the biggest threat? I'm in! Isn't the country divided every time there's an election? And how much of a problem is this divide? Worst case scenario: civil war. Best case scenario: Entrenched positions causing heated debates on social media and phone-ins. Much closer to the second scenario, I reckon. Maybe the odd violent skirmish at a protest. And besides, when the referendum results are more than reversed to 58/42 in favour of Remain, there'll be fewer people on the losing side to bang on about The Will of the People. ;-)
