the US left’s emphasis on social rather than economic issues

I don’t think it is the left that is emphasizing social issues. They are defending Americans in response to the right’s villainization of their next boogeymen to scare up more votes. The same right that then blames them for focusing on social issues. I implore those who are falling for this conservative ruse to start paying attention to what is going on rather than being taken by some of the dumbest tricks in the book.
