The Mighty Casey

The following plot summary comes from a Twilight Zone episode called The Mighty Casey broadcasted first in 1960:

"Mouth" McGarry, the manager of a broken-down baseball team on its last legs, allows a robot named Casey to play on his team. Casey has the ability to throw super-fast balls that cannot be hit. Eventually, after Casey is beaned by a ball and given a physical examination, the National League finds out and rules that Casey must be taken off the team because he is not human. Casey's inventor, Dr. Stillman, gives him an "artificial" heart to have him classified as human. Now that Casey has human emotions, he refuses to throw his fast balls anymore. He says that he feels empathy with the batter and does not want to ruin the batter's career by striking him out.

Is it me or did Casey turn into a liberal after getting that “heart” (which was just a ticking clock)? He certainly became politically correct. I know this is just fiction but I don’t think striking out a batter would ruin his career. It seems he became completely emotional and lost all logical thought—real strange for a robot. Then again for liberal robot it might make some sort of weird sense.
I am not sure what Rod Serling’s political stance was but I think he may have been poking fun at the left.
