Baby-making machines

It has been current topics on everyday news are about Hakuo Yanagisawa, who is a Japanese health minister, described women as "baby-making machines" also requested women to "do their best" to prevent a trouble that the birthrate in Japan is going down and down.
That was ultra impolite!!
I believe that he needs to take responsibility for this problematical statement and resign. Let me add this…. Even though someone who like, Shinzo Abe, the prime minister of Japan, should force him out of government, Abe has been standing up for him rather than make him to leave that I can't understand!!
