There were lies told on both sides of the 2016 debate. The losing side has chosen to make an issue of it being the reason for their loss. As you imply, this does not follow. The vote was not ‘stolen.’ If I am over sensitive it is because it is the tactics used by Trump so a bit rich really.
I think you're getting confused. You likened the Second Referendum marches to the assault on Capitol Hall, which is plainly ridiculous. And those seeking a second referendum were NOT claiming the vote was stolen. They were advocating for the chance to put the Deal to the vote. Hardly anti-democratic. Anyway, as you said earlier, best leave this to the Bear Pit!!
