I’m not sure how you seem to have missed my point, which I’ve explained in several posts. There are two explanations as to why Bercow was in a far right group. One is that he’s a racist, and the other, more charitable and perhaps more plausible one, is that he saw this at the time as merely a vehicle for his political and personal ambitions (you can read quite a lot into Bercow’s career, who just like many other career politicians, has simply chosen his political positions based on personal ambition). Either way, why would the Labour Party want him?
Was a racist, surely, seeing as you are talking about something from 40-ish years ago. And surely that brings up two other rather obvious plausible explanations for his membership of the Monday Club:
3. He was a racist, but has since changed his mind/grown up/etc.
4. He joined the Monday Club because he strongly agreed with other things they were advocating, was possibly uncomfortable with the racist views of other members, but put up with that because of his agreement on other issues (in the same way that pretty much anyone who joins a political party does so because they agree with that party on many things, while putting up with some areas of disagreement).
It's worth pointing out that during the 1980s the Monday Club wasn't generally seen as an extremist organisation: As I recall it was primarily a group that promoted monetarist/Thatcherite/small-Government policies, had links to the Conservatives and numbered quite a few Tory MPs amongst its membership. Times were different 30-40 years ago, and many beliefs that today would be considered unacceptable were relatively mainstream in those days (and vice versa).
I think the lesson is that it's not really a good idea to excoriate someone for opinions they possibly (but we're not certain) might have had 40 years ago, unless you have good grounds for believing they still have the same opinions.
Still haven’t covered his bullying allegations the results of which aren’t fully public yet. That’s more dry powder for his Labour career. Looks like a pretty unwise and rather desperate recruitment decision from Labour for me, and nobody has mounted any form of defence against what I’ve said regarding Bercow.
Labour doesn't, generally, recruit people in the way you seem to be implying. Usually people choose independently to join Labour (as I'm sure is the case for all the political parties) and sign up via their website. I would expect that in all probability, Labour had no advance knowledge or say in Bercow's decision to join - other than that they can reject his membership application if they see some specific reason to do so.
