I don't think referring to subjects in a considerate and understanding way using language acceptable to all is diluting anything and someone who can't mange to do that needs perhaps to examine why. If the views to be presented do deal with issues that might in some way disturb a section of society then that would need to be tackled in a sensitive way. Many such subjects are and all should be.
How can you ever present a subject using language that is acceptable to all? It just isn't possible. Everyone, including those with MH problems, has their own idea of what is 'acceptable' and what is acceptable to one might not be acceptable to another.
How can you sanitise a subject / issue to that extent?
I understand that some people's mental health is fragile, and there is no reason not to take that into account. However, University is traditionally an institution where ideas, assumptions - as well as facts and science - are examined and challenged... in the lecture halls and debating rooms, if you dilute the terminology and language to such an extent - for fear of offending someone, then you will change the whole ethos and so much will be lost in the drive for diplomacy that they will no longer be a seat of learning.
And no one individual has the right to decide for others what he thinks they should be allowed to hear. If the whole auditorium rises to its feet to protest, there might be a case to answer, but a handful - or even fewer people - saying they find something offensive and calling for no-platforming on that basis is wrong.
Democracy usually accepts the majority 'vote' and if the majority are not offended, then the majority rules. That's the reality.
