Hi Pallisers, I think my comment you repeatedly quote is as honest as any other in that it's born out of systematic observation and is factually based.
If you have a problem with my observation, which you have quoted, then I'm sorry for upsetting your delicate sensitivities, but I'm not about to lie and say that Americans I have observed, in general, are quiet, timid and mild mannered just to please you.
In my experience they aren't polite, aren't quiet and aren't humble, and they hog space. My observations lead me to the conclusions that of the Americans I have observed, they are rude, loud, space and resource hogging, arrogant, culturally insensitive and ignorant.
Now if you lived where I do and saw and sadly heard the amount of young American red blooded students as I do, (USA! USA! USA! chanting) then you might come to the same conclusions.
In general in my experience, I find young American students and tourists to be loud and pretty obnoxious and culturally insensitive. This is my honest factual observation, and I do realise yes, it's easy to stereotype and I haven't sampled the entire American continent, so we are talking about a meagre 50 years or so of my observations of students and tourists.
We have a different opinion. Doesn't mean my comment is 'unacceptable', it's just different to yours. It's called my opinion, and it is based on my observations: as far as I know I'm entitled to express my opinion freely, as you are yours. This is called debate.
I will add that I have sampled Americans on USA soil, and found Americans living in major cities tended to be more polite and quieter. But then as the saying goes, "an armed society is a polite society". So maybe the fact that Americans can carry guns actually encourages them to try not to antagonise on home soil as they could be shot by their fellow Americans. Just a thought.
