However, I am uncomfortable with a few parts of the language too. I agree "cowardly" seems unfair given that c4 had the balls to show it in the first place (the press release does not give them credit for doing so), we don't know the details or quantity of the threats received, and it's not for us to tell c4 staff to put their necks on the line if that's what they believe they'd be doing. Better to offer our support if they reconsider the cancellation, explaining why we think they should, rather than sounding like we are demanding they do so.
Except for some of the quotes from Maryam, most of it is fine, especially the stuff highlighting the slippery slope of letting the Islamists win and the consequences.
Yes, some reasonable points. I fully agree with the sentiment and text of the letter, although you're quite right that an acknowledgement of the fact the Channel 4 commissioned and broadcast it in the first place could, and probably should, have been included. With regards Maryam's comments, which were also included in the press release, I think it is quite right to highlight the challenges faced by descenting and ex-Muslims and to point out that when others back down in the face of threats, it is to the detriment of those who are unable to. However, I agree that the use of the word "cowardly" is unfair, particularly given that we don't know the exact nature of the threats received. I will discuss this with Maryam.
To address Blade Runner, I completely disagree that because this was a private screening, which could be seen as "little more than a social gathering", this is no longer an issue. In fact, I don't see it as being at all relevant. Threats and intimidation have caused a change in behaviour, and that is unacceptable. The complaint that you both raise, which I think is valid, is who should be criticised.
