I also think that as the list of "-phobias" grows ever longer it will become more like a paranoid index of grievances than a guide to important questions of everyday life. Worse, having a -phobia attached to you risks becoming a group's proof of existence and badge of honour.
I found three photographs. The first shows a meeting of the University College London Philosophy Society held on 17 February 1969 to discuss "Free Speech". At the table on the left G.A. (Jerry) Cohen lighting a pipe, on the left Ted Honderich, both UCL philosophy faculty; me in the middle.
The second dated the same day - so the events were clearly linked - the platform at the Friends Meeting House with the clock showing 7.15 pm. On the left, standing, Humphry Berkeley, me seated and looking down, the Chair John Shipley, John O'Keefe [ who must be the American post-doctoral student who later became a Professor at UCL and Nobel Prize winning physiologist], Anthony Lester of the National Council for Civil Liberties, unidentified person on the far right but whose face I know ...
The third, also dated 17 February 1969, shows Althea Jones-Lecointe at a meeting on the same day. On the platform, I identify the figures now as from the right Nigerian writer and Black Power activist Obi Egbuna, Robin Blackburn and standing at the microphone Oxford philosopher Michael Dummett (who I knew from the Oxford Committee for Racial Integration OCRI of which he was a founder). The radical line-up here makes me think that this could have been a Socialist Society meeting and I would have been able to invite Dummett. So I may be somewhere on the platform to the right of Blackburn.
Google tells me that John Shipley - now the Liberal Democrat Lord Shipley - was President of the University College London Student Union in 1968 - 1969 so this event must have been a UCL-organised affair and given the three meetings on the same day, would have been part of a Day of Action.
And now I discover (thank you Google!) from a UCL Alumni publication of 2008 that it was indeed a day of action timed to coincide with a visit by Enoch Powell to UCLs Conservative Association:
What strikes me now about these three photographs is that the platforms are 100% male and apart from Egbuna, white. I do not know who the photographer was but the three photographs must have been given me at the time and the one of Jones-Lecointe because it was the Socialist Society meeting.
I am now in some doubt about my original confident assertions: either no one (not even Soc Soc) tried to No Platform Powell's visit to the Conservative Association of UCL or else the attempt was unsuccessful and Soc Soc opponents then pooled its efforts along with others into this broad-based Day of Action (and then I think: which may even have had some support or encouragement from UCLs Provost, at that time Lord Annan)
