I have had a think and am going to have another go at articulating my position.
BC is effectively saying to NF, "don't say that a politician is responsible for a terrorist atrocity. If you do, the finger will point at you." Is that a fair paraphrase?
So, this is why people are saying he is trying to shut down and silence NF. Because he is saying "you can't say that". He could say any number of other things - "you are wrong because xyz, it is inappropriate because abc". He could argue. But he isn't, he is saying "you can't say that". And the reason he is giving doesn't really stand up to logical scrutiny. If BC really believes that NF is responsible for JC's murder, shouldn't it be said? Why is BC saying, effectively, let's all not talk about this, otherwise you won't come out of it well? And just because,attempts to shut down a line of discussion are not successful, doesn't stop them being attempts, they are just failed attempts.
Has anyone not see Jonathon Pie's Trump rant yet?

He explains how the left has lost the habit of arguing and debating, and that now it is all about saying "you can't say that". As he rants, it doesn't work.
And BC's tweet relies on the view that if we can say one politician is responsible for a murder, we can say another is. Everso slightly simplistic. We should judge each case individually. Are we really saying now that it is never right to say a politician's actions have caused murder? How about other deaths, can we blame them for those? Are we no longer allowed to blame Thatcher for all the misery her government caused? How are we going to tackle the growing threat of terrorism if we are not allowed to discuss the role of politicians in relation to it?
To clarify, I am not saying NF's comments were right. I am saying the,answer, if you disagree, is to argue, not to say "you can't say that".
I think this is what's been happening increasingly in political/public discourse over the last few years. Things have got mighty complicated, but instead of facing that and trying to understand the implications, the left (and I am discussing the left because that is my way of thinking and for me, the only hope for a better world) keeps trotting out simplistic soundbity type answers which then everyone latches on to and it becomes harder and harder to challenge. Incidentally I did read on another thread that HnH were one of the main instigators of the whole university no platforming thing, interesting if it's correct.
To summarise my lengthy post, people need to argue, not tell other people to be quiet. Apart from anything else, it doesn't work.
