Depends on the definition. Are you talking about sex, sex characteristics, gender role, gender identity, gender expression or socialization?
Sex cannot be changed (for humans) (yet). But things are a bit more complicated for people who have never produced any gametes and especially for people with an ovotestis. Should people who have never produced any gametes be classified as not belonging to any sex, or should they be classified based on how similar their gonad cells are to the cells of people who do produce gametes? In general, females are born with their gametes, so they are clearly females very early in life. But males only start producing gametes during puberty.
For sex characteristics people can change some of them (e.g. hormones and some things related or caused by them).
For gender roles, they change through time as cultures change. So your gender role is not the same as your grandpa's and it can even change during your lifetime. Also some people are considered by the society as a different gender role from what they were considered earlier.
It appears to me that not only a particular gender identity is on a spectrum, but also having/not-having any kind of gender identity seems to be on a spectrum. For this reason, I think it might be possible to acquire/change/reject gender identity for some people, and for other people it might not be possible to modify it in a meaningful way (e.g. people with gender dysphoria). This is my opinion only.
Gender expression can be changed totally.
When living long enough in a different gender role, one can be exposed to different socialization and it might influence them.
So what's the argument here?
Lord Myne wrote:The way they behave and think are so different from girls.
But psychologists say that there is not much culture-independent difference in thinking between men and women, besides some fairly trivial things like 3D mental rotation and such (ON AVERAGE ONLY of course, not for everyone, the differences are tiny, and it's not 100% clear what the causes really are). And behaviour of the genders is different in different cultures. E.g. there are cultures where men are the beautiful ones. There are cultures where women hunt. There are cultures where cooking is considered a men's thing to do. So what's the argument here?
Lord Myne wrote:But I must admit biology screws this up and sometimes gives girls and boys the wrong parts.
That's mostly true, but I wouldn't call them "wrong", just different from the average ones. "Wrong" is a word suggesting moral evaluation, but why different parts are bad/evil etc.? You don't like them?

Again, are you talking about sex, sex characteristics, gender role, gender identity, gender expression or socialization?
