I do think both sets of voters were intelligent enough to understand the technical rules under which they were participating.
I do hope both sets of voters are mature enough to cherish the fact they can participate in a democratic process, and accept the results.
Really! I think it is practically irrelevant since all people could do was register their vote yes or no (or abstain) or in the US case vote Trump /Clinton or other. They had no say in how that voted would then be collated to register the final decision.
I think that accepting the results is all that can be done. However accepting and saying nothing is not the only option in a democracy.
