One of the attractions of Twitter is that it gives people the ability to have a dialogue with people who are generally used to broadcasting. One of the downsides is that you can engage with people in a civil way but they can block you without reason. Their choice I guess.
I challenged Professor Dr Brendan Cooper, President of the Academy for Healthcare Science, on his very political comparison of current Secretary of State for Health, Jeremy Hunt with Labour hero Nye Bevan. His response was to block me. He could have made his case. If he was busy he could have ignored me. Fair enough. Blocking someone making an argument is the equivalent of yelling “Shut up”. Nice one professor.
