============
Why would such a rude and opinionated post like the above deserve a rational answer? I don't wear spencers etc, but I'm still offended, because you don't seem to be aware of personal choice. Most of the people who sport beer towels, etc, DO dance, I suspect you wouldn't have time, whilst rushing up to the decks to check, the matrix number and turning circle of a particular 45.
And the other extremely rude thing you've said....."If the answers aren't rational don't bother". Rational by who's logic, your own? So if someone puts an opinion, and it doesn't agree with your own you reserve the right to veto the messages, cos they don't meet your criteria. What's it like to be omnipotent?
Your last sentence says, "If anyone is offended by the above, this message board is about opinions". So how about following that to the letter, and accept others may have differing opinions to you, and also accept that they have a right to voice said opposite views.
