It's Chik Fil A all over again. Remember a few years back, IIRC, they had taken an anti gay stance. Supposedly, there was to be a boycott of the restaurants. Detractors vs supporters. Supporters were lined up out the door to get a sandwich. Their highest grossing sales day, ever. It didn't effect me. I have only tried doing business with then once, but they were closed because it was Sunday. This was back in '75. Boycott? Nah, just no interest since then.
Papa John's? In 2012, his business ethics was released and every one on the left freaked and called for a boycott. I couldn't do it because I stopped doing business with the company in 97. Why? Because of the lousy service. Funny that I noticed it back then but nobody else did.
No, I rarely do the knee jerk boycotts because the actions of the corporations hit decades earlier.
Streep? I respect her as an actress and understand she is at the top of her craft, but I think the only thing I've seen her in was a comedy called Death Becomes Her. Boycott? Nope, she just choses roles in films that don't interest me.
Ask me my least fave entertainer, I'd say Dice Clay. His comedy routines aren't funny. Shame, as he's a damn good actor but box office poison.
