thank you very much. Maybe i'll be able to understand the hostile comments better then. To be honest the reactions of some make me sad. I like to post here and i even more like to read the interesting topics. The shark subforum is super interesting for me. I also got alot of positive feedback from many members here. One helped me alot via email as my cooling system in my coral tank died. Thanks him my setup made it through with just minor damage. But some react very agressive towards me without no reason. At first i didn't know why but Alan told me why that happens so i understand better now. I believe it's a cultural misunderstanding. They may never have left USA so they don't know how to react towards a foreign person, different cultural backgrounds and opinions. If you read Alans post which he did send me he said, those feel angry when USA are critisized. I did not critisize USA. I love Boeing. But Modest Man feels attacked because i was writing about the problems Boeing has. He feels attacked and felt exactly into the typical behavior which Alan explained me.
