This isn't true, in the slightest.
In Wales, Labour gained 3 seats - and has put many seats (Aberconwy, Ceredigion, Clwyd West, Preseli Pembrokeshire, and the Vale of Glamorgan) back into play with an average swing of ~10% in its favour.
As for Scotland, I think many Scots will see Labour as a viable alternative to the SNP next time around.
I was talking about the last election, not future ones that are far from certain. It just seems odd that in parts of the country that have traditionally always been Labour, but where a viable left-wing alternative exists, much of those regions chose the alternative rather than Corbyn's Labour. Had he been the messiah many of you fellas believe he to be who is wrestling control back and leading Labour into the socialist chosen land, you would think Wales and Scotland would have come flocking back? Yet the Tories did better in Scotland than Labour did, which is frankly quite staggering.
You must surely accept that there is a strong risk that you're residing in a Corbynite echo chamber that doesn't allow you to see the wood for the trees?
