Canada is in America after all, so it would make sense to call them that. I get upset at all the people on the news these days saying "America" when they mean the United States. Ask someone from Venezuela if they are American and they will say they are. America is the entire western hemisphere.
Anyhow, I don't think "Jewed" is a very evil one. I am not Jewish though, so I can't really feel the insult. Of course stereotypes are there for a reason. If something is statistically true most of the time, we begin to assume and then we have prejudice. I can say it is unfortunate and closed minded to assume all of a certain race/religion/etc. will have the same traits. Often you will be right, but you may hurt someone who trancends the stereotype by grouping them together. We commonly use the term ghetto rigged, which is sort of messed up, but then again people say oakie rigged and they are talking about white people. You make a blonde joke and you are talking about white people. How 'bout a Pole joke? Everyday as an average white male you get stereotyped and insulted, and we just take it, because we are the majority. Watch an hour of Prime Time TV for an hour and see how many times the male is made out to have inferior intellegence. What I am getting at is that people are too sensitive. "Jewed" evolved out of a common occurence, someday we may say "Habibed," since Indian hotel owners seem to be the new scammers. I work in retail, so I know all about who are the tightwads. Yes, Jewish people tend to be rather hawk-eyed when you are selling them something, as are Asians and Indians. They will point out the smallest discrepancy to save $.08 or something. There are white people are like this too, its just less common. People who have things made, like family money or government money, don't tend to watch money too closely. These are the ones who are going to get ripped by people on the up and up. Indians are notoriously upward bound. I think it just comes down to cultural values, and there are plenty in all parts of the world that will take you for everything they can get. In the end, the tightwads end up with more money and that is seemingly the more intellegent way of living life. So if Jews are notoriously schiesty, than that just makes them smarter than the people they are making their money off of.
