This incident underlines the downside of social media - everyone has an opinion, and now, everyone has a worldwide platform for that opinion.
I have no truck with Twitter, purely because I have no interest in the daily ramblings of strangers, and I fully expect them equally to have no interest in mine.
The problem occurs when someone with a high profile, a 'celebrity' for example, uses Twitter.
What years ago would have been a though voiced in the bar of the pub, or over dinner with friends, and rightly left there, now becomes available to the world of similarly garrulous keyboard monkeys who can't wait to shout down an opinion they think is wrong.
I would suggest that if you are going to climb on the social media bandwagon, you decide well in advance to be seriously selective about what you are going to enjoy, and maybe respond to - 1% of what you see, and ignore, or read and then ignore, the other 99%.
That will stop all this ludicrous nonsense once and for all.
