I read the article which has been reprinted
here without the paywall. She recognizes the absurdity of her own outburst when she says:
"If one of my grandchildren yelled something that ridiculous, I’d have to stifle a laugh."
What provoked this 30-minute tsunami of recriminations?
She is triggered on this particular day by "a small, thoughtless, dismissive, annoyed, patronizing comment.".
Why does this careless or inconsiderate remark summon up a lifetime's worth of frustration with male "culture"? She doesn't say. Perhaps she was having a bad day.
Some of the male behaviors she identifies range between the criminally pathological to simply misogynistic. I can relate to her frustration regarding the worst behaviors having yet to be completely eradicated. However, she seems to expect that perfection can be achieved. She also overlooks the fact that men are not the only ones who make sport of mocking the opposite sex. Women also engage in that particular pastime when discussing their husbands and other males. Female comedians depend on male stereotypes for material.
She needs to manage her expectations. Perfection is not possible. Men, like women, are only human. She also needs to be more considerate of the person with whom she has shared 50 years of marriage. You don't use the person you profess to love as an emotional punching bag. That makes you, not them, inconsiderate and mean-spirited. She also seems to think that controlling behavior is a failing of the male sex alone. She must be blind to all of the seriously controlling women out there. The need to control is related to personality types and sometimes early trauma. When it can't be done directly, it is done surreptitiously, through emotional manipulation. Women specialize in the latter. Personally, I'd rather deal with direct attempts at control. It's easier to challenge.
Anyway, her statement to the effect that she wishes all men dead, was incredibly absurd and childish, like something a frustrated 13-year-old might say and just as meaningless. She didn't mean those words. They were just used as weapons to inflict emotional pain. A streak of controlling behavior of her own, for which she seems to lack any personal insight.
