Being a soft-version of your opponent is why David Cameron's mandate GREW, instead of shrank(even with Cameron's record having more Losses, than Wins on it). Labour should be left, or it should rename itself. Corbyn by the way isn't all that left, based on his agenda, he's more of a Humanitarian-Democrat, which puts him left of the middle, not even close to really being a left politician.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
