If they have a 2nd petition I'm sure it'll include an option to say "I want to stay in the EU", which would be the same thing: repeating a vote until we get what we want.
Easily solved with instant runoff voting[1] for the entire spectrum from Remain to No Deal.
No one wastes their vote voting tactically, everyone gets their voice heard, and we get to choose exactly how we shoot ourselves in the foot when Leave wins a 2nd vote.
I mean how could Leave lose? It was the will of the people, they'll clearly vote the same again. /s
Better than the current game of 3d chicken we're playing right now.
So instead you advocate we don't get what we want because all decisions are meant to be final?
"I'm sorry, you cannot return this jumper you bought online because even though it doesn't fit you, you've already decided to buy it and all decisions are final".
