anniebach What is the significance of you calling McDonnell McDonald, and why, as someone suggested, is it ironic?
I can find no reference to the Corbyn-supporting group Momentum having the tag line "we live for him". There is another [Christian] organisation called Momentum which says that their aim is "to live our lives for him/to live our whole lives for him". Perhaps it is that group which uses that slogan.
Of course, it is troubling that the Labour Party seems to be tearing itself apart but if, as you say, the MPs who are revolting against Corbyn have the support of most of the people who vote, or would consider voting, Labour, then in the event of the party splitting, they can rely on that support to re-form the party and bring it more in line with what, according to you and others, most supporters/voters want. Any such new party will be favourably received by the media - unless it steps out of line again by pursuing policies that oppose the privatisation of public services/are vaguely reminiscent of the party's socialist roots.
I feel it is those Labour members who support Corbyn who should be upset. Not only do they have the might of the media against them (it is noticeable how unbalanced the commentary is - with commentators being almost exclusively of the "let's sneer at Corbyn/Corbyn's supporters" variety), but also the very MPs whom they elected.
I note your comment that you avoid links because so many are from "the extremists". Who exactly do you consider to be "the extremists" and why?
In fact, the article that Gracesgran provided a link for was extremely interesting and, as far as I could see, had no particular party political leanings - though it did conclude that, whatever happens re Brexit, he thinks it will result in a "betrayal of the white working class". Whilst I tend to agree with that, I don't don't know why the white working class is deemed to be a special case. I feel that a non-white person can just as easily be in an unskilled/semi-skilled job or unemployed and thus be part of the growing number of "precariat" who are continually being betrayed by parties that appear to be more interested in maintaining the status quo - with perhaps a little tinkering around at the edges - than in making real, progressive changes.
