Sexist is discrimination based on gender that causes harm. Sexist is caring about something like this that does not affect you directly.
We should all be neutral about this. It is a fact, it is an observation and there is not necessarily a motive behind it (although for some there might be). Sex sells and the whole world is buying. If women earned more than men there would be no need for child support.
For the large part most feminists are as sexist as those they oppose, and in every walk of life (whether it be to do with race, gender, religion, politics or sport etc.) those that hold convictions are seeking dominance over others. If we look at the positive of every action, the outcome is more likely to be good for everyone.
We should marvel and cherish those who have been able to achieve greatness and hopefully with the winnings of their efforts they will realise that others have supported them, that others have helped them achieve and they will give back to others, whether in life or at death.
And while debate, free expression and constructive criticism are necessary and virtuous, rousing feelings of anger is not. Whether in yourself or others.
