Amnesty, National Aids Trust, World Health Organisation and Terrance Higgins Trust all said that doing so would be bad for public health.
Instead, after one 90 minute interview he just decided to take Phillip Lee's word.
As a result several good, talented, committed activists have quit the party.
The leadership does NOT have expertise on LGBT topics but it refuses to consult with those who do.
It's one thing for the party to consider something carefully & then to make a tough judgement call despite knowing it'll make some people unhappy.
But here it's clear they didn't consider it at all.
In most interviews Phillip Lee has had since defecting his views on immigrants with HIV have been brought up. In response he's doubled down on them and threatened to sue Lib Dem members for defamation.
As a result, Lee's record has been noticed by the media. They're already sniffing around - and this story has legs.
That doesn't feel like a worthwhile trade to me.
If you wanted a recipe for ensuring this story haunts us for ages then you've managed it through your refusal to listen beforehand and your continued refusal to listen after the fact.
You're driving good people away in exchange for nothing of value.
