My grandparents wouldn't buy anything made in Japan or Germany back in the 40's...don't buy anything from a blue county or hostile country.
That's a start, but we also need to stop pouring our money into the companies and media that are actively working against us, even if it means doing without.
But after years of saying this, it's clear to me that our outrage will last only until the next ball game or the next hot deal at Amazon.
