I absolutely hate discussing gender differences, as I am easily offended by such generalizations, and, while I fit the conclusion that I reach, I am anything but 'masculine' in the societal sense. However, I believe I know why the topic is so offensive, and thus am trying to remedy it. But first, I must say this:
These are only generalizations. There are always exceptions.
Anyway:
I think we can all accept that there are differences between men and women. However, people seem to be determined to divide up the differing personalities in terms of better and worse. This is a critical mistake, as it will invariably offend someone. For example, I think we can all agree the following statements are offensive and immediately label the speaker as an uncouth swine:
'Men are strong, and women are weak'
'Men are dominant, and women are submissive'
'Women are smart, and men are stupid'
'Women are deep, and men are shallow'
Fortunately, the days where these type of statements are acceptable in public are past (I think), and we as a society have moved on. However, our current gender generalization assumptions are not much better. All we do now is try to balance our generalizations, such as this:
'Men are strong, but women are clever'
This is equal, more or less. However, it is equally insulting, not equally praising, as most people will only see the insult against their gender than the praise.
Thus, in order to generalize, we must do so in a way that stresses that each gender is equally valid. Here's a good first take on it:
'Men and Women see the world in different ways.'
That is not offensive, as there are few ways of seeing the world that are immediately offensive. However, at present this is a tautology, only stating the opening premise. We must be more specific. Thus, I arrive at my generalization, which I think manages to be non-offensive:
'Men are precise, and women are subtle'
Notice how these are not opposites. When one is presented with two opposites, the immediate reaction is to take a side. By keeping the generalizations skewed, there is no obvious 'side' to take. Notice also that there is no immediate insult opposite the words. 'Imprecise' is obscure enough that it is not directly offensive, while 'unsubtle' is not generally perceived as an insult.
Also, there's the and. By using and instead of the more common but, I stress that neither of the viewpoints are meant to be better or worse than the other. This is the most critical point.
I have not mentioned transsexuals, bisexuals, homosexuals, asexuals, intersexuals and people whose sex does not match their gender. This is because I do not know enough of them to generalize about them. All I will say is that my generalization does not necessarily apply to them.
