Not the one you were asking, but I agree with them, so might give it a shot!
You know how sometimes you do something stupid and then have to live with the consequences and then next time you don’t make the same mistake?
For example, when you fall off a bike. Or grab the very hot stove. Or when you vote to leave the EU.
If you weren’t allowed to make mistakes, would you learn anything? Would you have learned to ride a bike if you only ever used it with the helping wheels for fear of falling?
Saying that people’s will should not be respected is very far from what democracy is. The will of the people is ultimate in democracy. And in the beginning, people will make mistakes. The only way to stop making mistakes is by practicing further.
