Personally, I have NOT found Europeans to be rude or disrespectful of my views. Whether at home in America, or abroad. I think the media portrays something different. Maybe to divide us? Again, this is what I THINK...just my opinion.
I do know a Canadian who personally told me that Americans are aggressive and always looking for a fight. My response as I jumped in his face (just to get his goat...lol) was, "Yeah, so, you got a problem with that?" HA HA HA...I'm not a violent person, and I'm not into stereotypes, but that sure was fun!
I suppose each of us has an individual experience which would form an opinion to post as an answer to your question.
Great question, BTW, Dax!
