You make a fair point but I do disagree with this analysis. Had UKIP been represented in the Commons on a proportional basis, the British public would have witnessed the brawling in the corridors of parliament which they descended to in the EU parliament, the gratuitous insults handed out by Nigel Farage and the uncooperative destructive bullying which they engaged in instead of reasoned debate. The British electorate would have seen them for what they were and they would never have gone beyond the status of fringe extremists. In my opinion it is precisely because they were kept out of parliament that they were able to present themselves as embodying a popular true faith which, in fact, nobody subscribed to in the form which they were determined to realize.
I suppose it is possible 80 UKIP MPs would have shown up UKIP for what it is.
But I would have thought a bigger danger for the UKIP haters is the public would come to like what they saw.
For UKIP haters, I think their best protection remains an electoral system the keeps UKIP on the outside of the tent.
