  2. The bible exhorts men to love their wives……but it tells women to respect their husbands…..because women are incapable of (romantic) love. I know, I know, 2000-3000 year old writings are probably without merit……………right???????

  4. Some American women seem to be obsessed with women power. I hope the US will soon have a female president so that all the shrill American feminists with a victimhood complex would rediscover the French proverb: The more things change, the more they stay the same.
    Many countries already had female presidents or prime ministers and those countries still have the same problems as they had before they elected a female president or prime minister.

    When Obama was elected as President, many pundits predicted a lot of wonderful things for America under his Presidency. Now that Obama has come and gone, we can all ask ourselves what have really changed for race relations, class division, the gap between the rich and the poor, gun law (did less or more Americans die from guns under Obama's presidency?) and so on.

    Many feminists keep claiming that women are nurturing and caring and a female prime minister or president would look after the poor, the disadvantaged, the minorities and so on. Well, many other English-speaking countries sharing very similar values as those of America did elect female leaders such as the UK, Australia, New Zealand. Why do American feminists not ask the people of these countries if the gap between the rich and the poor has narrowed or widened since they have elected their female prime ministers? What about other social and economic problems? Have those problems been lessened?

    America will not get better because of a female president. America will get better when Americans think and act rationally on a wide range of issues.
