Many in public life hold both hard left and hard right political views. However, undoubtedly it is how such people carry those views in their everyday working lives and perhaps more importantly within the interactions such people have with others.
By example to the above, Len McCluskey the General Secretary of the Unite Union has always made no secret of his strong Marxist views and how he would wish for a British government to set policy in that direction. However, in 2011 a bitter industrial dispute broke out between British Airways (BA) and its company cabin staff. The dispute dragged on and it was arranged for McCluskey to become involved in trying to negotiate a settlement jointly with the CEO of BA Keith Williams.
Williams had a reputation as being a "hard nosed capitalist" and had been brought in to BA to completely revamp its operations following poor trading results. Against that background, no one on either side of the dispute felt that any settlement would be forthcoming when judged against the backgrounds of both men
However, in less than three days, the same number of meetings and dinner in a very upmarket London restaurant, a comprehensive settlement was brought forward and agreed. It would seem that McCluskey and Williams had put aside their very different views on how the world should be governed, and had instead settled on pragmatism to end the dispute. Indeed it said the two men got on so well in each others company they have remained in contact ever since.
Therefore, it does not follow that because Jeremy Corbyn holds hard left-wing views that any future government led by him will follow a Marxist agenda. Indeed, the present policies of the Labour Party many would argue are very far from that.
As stated anyone can hold hard left-wing or hard right-wing personal political views, but it is how such persons carry those views in their everyday lives that is most important, and it is in that such persons should be judged.
