I think this has been overblown and this type of language control will in the future be used to silence people and sack them and will probably be made illegal. It was insensitive but that is at far as it went.
I think the MP who was on TV last night is overdoing it and now they want Ken to apologise to all people with mental health problems.
I think it is being used as a stick to beat Ken with because he disagrees with them over Trident and they would like him to stand down.
Unfortunately we don't have a Donald Trump in this country, but can you imagine if Red Tories tried this tactic on Doanld?
