Here’s my final take on the matter, summarised neatly.

 - It was a terrible error of judgement, and an extremely revealing one at that, for the Union to invite Griffin and Irving. The Union was under no obligation to bring these people to Oxford, and in my opinion should never have done so.

- However, seen as the Union is a private institution, whose members voted 2-1 in favour of the event going ahead, that must be respected if one believes in freedom of speech (both for Griffin and Irving, and for the Union, incidentally).

- Consequently, those protesters who said that this was not a freedom of speech issue either hadn’t thought hard enough about what freedom of speech is, or were being dishonest.

- In the end, i was mighty pleased that so many people turned out to protest. Regarding the technicalities of the issue I likely disagree with many of the people who were protesting, but regardless of that, I think it is a wonderful and important thing when people do turn out in force to let Griffin et al know they are not welcome, whatever the Union takes upon itself to do.
