The industry is crawling with them now. The patriotic conservative entertainer/actor/musician is a rarity these days.
How right you are. The "reverse blacklist" against conservatives and believing Christians is far stronger than the 1950s era blacklist against Communists and their sympathizers. The only media venues where conservatives and believing Christians dominate are in talk radio and country music. Leftist led boycotts invariably fail when they go against persons whose market is supported by conservatives, most notably the boycotts against Rush Limbaugh, Chick-Fil-a, and Duck Dynasty. Conversely, ask the Dixie Chicks how well their careers went after they denounced George W. Bush in England.
