How exactly are women castrating men? What are women doing that You're so angry about? Not responding to sexual advances is the only example you gave, anything else? You're doing the EXACT thing you are accusing women of doing, blaming women for all of men's misfortunes.
I'll tell you why: because he has been castrated and must bow and accede to every wish of his wife. The whole show is based on the premise that he MUST NOT, under any conditions, offend his wife, which of course he does continually but always remains subservient to her.
