I din't say they were the original aim. I didn't say that they are the only people being silenced.
I said that there are no 'basic regulations' driving any of this, and asked whether there were examples of other topics where universities (many of whom are running scared of Stonewall) have silenced (or curtailed) speakers. That is very different from students cancelling a talk after a vote by a society's members.
I am not arguing for the sake of it, and not trying to be 'on a winner'. I find the notion that 'basic regulations' are there to 'protect vulnerable' students (a) troubling, and (b) I know it is untrue.
A lot of nonsense is spouted about universities and students, often by people with no experience of them since they were students themselves decades ago. People believe what they read, as seen reflected in posts on here, and often it just is not true.
It is unfortunate that this has arisen on a thread about someone wanting to speak about trans issues, as we obviously disagree about those, but that is not what is driving my wish to have the record set straight. I would feel the same if someone claimed that a speaker from, say, the Lib Dems (purely as an example of an innocuous group with whom I disagree) was being 'banned' by 'a university' because of 'basic regulations' designed to protect 'vulnerable students', and you got arsey with someone questioning this by saying that if they didn't understand that some students are vulnerable there is nothing you can do.
Who do you think would make decisions about whether to allow speakers on every module, to every society and to university-endorsed events such as public lectures, research groups, consortiums and so on? Do you honestly think that anyone has time to go through the scripts of all of these people and decide whether vulnerable students may find them distasteful? Do you even have any idea of how many of these talks there are in any week, let alone a year across a university?
