The only Americans I have ever heard who think that the other side shouldn't exist, are those on the right who frequently express a desire to "get rid of" leftists. This will not end well for you.
Canadians may disagree but 92% of Canadians think their fellow Canadians are "good people".
In fact, only Americans hate and distrust their fellow Americans in this manner. From the days of Ronald Reagan, the right wing media has promoted the idea that the left are out to destroy the country.
Started with "left wing media cannot be trusted". You've done this to yourselves.
