The problem with a second referendum is that it would put us into more turmoil than we currently are. They had a chance with the first referendum to put some obvious and clear parameters in to avoid ALL of this. And, of course, they're Tories...so they totally ####ed it all up.
It's what Tories do. When they're not doing Tory stuff like flogging off really important national services, throwing hard working (class) people on scrap heaps, and of course the important role of killing swathes of the population off.
