Cape May - Why does the liberal left constantly try to find fault with those that try to live according to their convictions? Now they are going after Chip and Joanna Gaines, the producers of the highly successful show, Fixer Upper. The issue; the Gaines Family attends a church where the pastor does not believe in same-sex marriages. The Obamas attended a church for years, where the Pastor Jeremiah Wright still continues to preach hate toward America, yet nothing is mentioned by the liberal media.
