Hello martinatreue, I got it from your posting that you have not followed all of Paradorn's matches lately as we did in Thailand.
Certainly you have not watched the Davis cup matches between Great Britain and Thailand in that took place in Birmingham a few months ago. The English crowd is more polite than the Parisians but they were not on Paradorn's side. Paradorn lossed to Tim Henman and I think Paradorn bowed to the crownd too.
Later in Tokyo when he lossed to Calsen and in Madrid when he lossed to Novak, he definitely bowed to the crownd which were very "neutral" in cheering both side. You can argue that Japanese are also Asian but Paradorn just knocked out Suzuki the home's favourite before.
Have you seen the final match in Stockholm? The crownd were full of Chileans who came to cheer Rios. (There are ~40,000 Chileans living in Sweden). OK paradorn took his second titles there. He still bowed to the crownd who were shouting "Rios!, Rios!" at the time he bowed.
Please don't be prejuded. This bowing to the crownd is commonly practice by Thai boxers. After the matches, both sides thank the crownd for watching them. Paradorn is also a good Thai boxer himself.
Hey, I also like Andy Roddricks a lot. The match he exchanged aces with Paradorn and played till tie break is remarkable.
It's just a game.
