In reply to mutt:
To address a few things in your answer to me:
"However you want to attack me"
I don't want to attack you. You wrote about predictable dislikes so I thought I'd be bold enough to explain my dislike.
"it doesn't change the fact that flying is totally unnecessary and a major source of pollution."
You are of course right. But as Mike says you come across with the wrong tone. And my point was that you also come across as 'holier than thou' and hypocritical. In your answer to me you don't explain your double standards. How is it OK for you to fly and not others? Perhaps people might respect your views more if you could explain that?
"I hope the OP enjoys his holiday in Greece."
Again, an example of your 'smart' and sarcastic comments which do you no favours in gaining support for your views. You clearly don't mean this genuinely otherwise you wouldn't have guilt-tripped the OP earlier in this thread, so why say it?
Just take a moment to consider how many dislikes you're getting. I bet, like me, all of the people disliking your comments actually understand the science and actually agree with your fundamental point that flying is unnecessary. So why are they disliking? Because of your tone, I suggest.
