You know, I think that we start doing wrong by calling people men or women,
I think it would a really huge step by not saying to your children what is a boy or a girl, at the end we're all people. People that will work, will travel, and so on. So try to see a little bit far than usual, I swear nothing wrong will happen. All you got to do first is to understand it yourself, the rest will be easy
That's all very well and good but these 'people' are still split into two separate and noticeably different groups. One half of people are susceptible to testicular and prostate cancer, they need to be checked and treated for this. This group also has the capacity to impregnate 'people'.
The other group are completely immune to any of this but can be impregnated and are susceptible to ovarian and cervical cancers, for which they need checking and treating. The first group don't need to worry about this at all. But it really helps if you know which group you belong to - hence separate nouns. 'People' suffer from testicular cancer isn't a message that is particularly helpful as it doesn't specifically target any particular group of people, leading to the ones who don't need to worry worrying and the ones who do need to worry ignoring it. A huge waste of time and resources ensues.
Our biology is different and it is important and it needs to be catered to - it is important to know which biological half of the species you fall in, so we give each half a name - 'penis people' and 'vagina people' seem a bit on the nose though, so we use 'men' and 'women'
Our difference in biology does not mean that we have different capabilities when it comes to none biological elements of humanity, such as enjoying drawing or being good with computers 'people' is good enough in these cases, but we need to be more specific for sex based differences.
Men, however, have believed that women are inferior for millennia. They have justified this belief by using our biology and attributing non biological aspects of our lives to it (women being not good enough for political life because of our wombs, the very idea of 'lady brain' etc). Our oppression was and is biologically based - 'some "people" think other "people" are inferior' doesn't really explain the truth of what is happening though does it? It obscures what is happening and makes it impossible to fight against.
Removing the words 'men' and 'women' or expanding them so that they are meaningless actively harms women and is to the benefit of the very men who seek to harm us, because we can no longer name what is happening.
'man' and 'woman' are very important words. Especially for women. And yes something wrong will happen if we do away with these words and we do understand that, thank you.
