In the comments to an earlier thread, this:
I am a journalist and have been "warned", in a manner similar to the one posted, by a social economics professor.
The "offence" was a summary of Lord Monckton's opinion that AGW is diverting resources, causing food price hikes and adds to human misery.
The threat was that the mere reporting of information would be taken as a direct adoption of Monckton's views and the writer and the magazine would be seen as oil industry shills. The prof threatened by phone but refused the invite to write his own two page response in the form of an article, not just in the letters page.
My temper is very elastic, but not infinite. Having recycled (certifiably) my last car in March 2000 and being a 100 per cent bike commuter ever since, I got pissed at being called an oil industry shill.
The lesson- you will be surprised how quickly these people slink back into the darkness when told unequivocally to bugger off. They are also very vulnerable to humor, probably because they are humorless themselves.
I've made a minor change in the punctuation to the first sentence to clarify the meaning.
