Pop singer Katy Perry has brought about the wrath of the progressive left by urging fans to set aside their political differences and reach out to their Trump-supporting family members and friends. She tweeted this weekend to her 109 million followers: “The first thing I did when the presidency was called is text and call my family members who do not agree and tell them I love them and am here for them. Call your family today. #FamilyFirst." Didn’t Joe Biden say himself, that we should put aside our differences?
