Tariffs and sky high audio prices.

There is plenty of empirical evidence that humans are becoming increasingly polarized. Mere difference of opinion is not responsible for this increasing polarization. Opinion is an admission one lacks surety, room for dialogue here. Opinions are being replaced with belief, particularly the kind of belief that conflates itself with objective truth.  

Add in new ideas of political correctness that celebrate overt disrespect and you have a perfect storm for emotional reaction

For far too many, emotional response and self perceived notions that one is in possession of objective truth preclude negotiation.  I question how long zero sum games will define our negotiated interactions. With no light between competing visions of reality I can't really see this turning out good.

Nonoise, I just enjoy your colorful and articulate language.
Problem is that in my impression most participants, whatever their political inclinations, don't care about anything but significant selves and their wallets. First there came pilgrims pioneers and other real people, then Yankee descended and methodically have been transforming the way this place functions. We have the result of that. It is not New World any more, it is the old one in a new land. If you want an example of repetition you have it.
I suggest America threaten Canada with nuclear hit to get a better trade deal. We are being robbed by everyone. 

And I have a message for the Australian mate. You people sell yourselves to Chinese big time, you treat asylum seekers like animals and this is not your land anyway - that land belongs to Aborigines. Change or get out.

Most of the parts are made in China so expect all Audio Equipment to go up in price..
American made actually means "assembled here" of Chinese parts..

Original spirit of America is independence. Instead we more and more have the opposite. Independence is worth paying for, including with dollars.
