Please tell me I’m picking up the wrong end of the stick, however the above seems to read very much along the lines of “different choice to me = inherently wrong”.
Quite. It's a recurring theme in modern politics, and it's completely unhelpful and self-serving. All parties aiming to win votes rather than an ideological purity award need to realise you need to appeal to a cross section of people. Few people other than the completely indoctrinated are going to agree with a party's stance on everything.
One nation and broad church are Tory party cliches, but the reality is they've managed to capitalise on selling themselves as the best choice overall to many, even if you don't agree with everything.
Labour seems completely unable or unwilling to attempt anything similar. A recent example is a debacle where members of the Labour leadership and leadership contenders began threatening members with expulsion if they held an opposing view. That's insanity.
They seem set on a course to implosion they won't divert from. It's an awful situation, regardless of your political leaning, because we need an effective opposition party. Which, perhaps cynically, I increasingly think is the heart of the problem, swathes of the Labour Party are perfectly happy in opposition and have no interest in listening to the ordinary membership or wider supporters.
