What is a "male" or a "female"?

they want to abide by certain gender roles of the opposite sex mostly

Female produces an egg while Male produces sperm. It is currently impossible for two females to reproduce or two males to reproduce. A female is capable of giving birth, a male is never capable of giving birth. It is possible for some organisms to change from male to female or female to male, humans are not one of them. Anything beyond that, like females enjoying make up, is due to society.

If someone who was born male wants to live as a "female" who cares, just respect them and let them live their life. They aren't actually female but they are what society sees a female as.

Ah I forgot about seahorses, so some males are capable of giving birth but never producing egg.

I'm an FtM. I consider myself to be someone whose biological gender (where "gender" is a subjective sense of identity that is driven by our neurology) to be male, and my sex (where "sex" can refer to your genotype, e.g. chromosomes, or your phenotype, e.g. the combination of genitals and, to a lesser extent, secondary sex characteristics) to be female in every respect.

I don't really want to change the actual definition of "male" or "female" in the sense that biologists would use it, no. I would just like more people to grasp that there is more nuance to sexual dimorphism than "muh chromosomes," especially as high-level, self-aware social mammals.

When idiots shout at me, "You can't change your sex! You'll always have XX chromosomes," it's not that I disagree. I just don't think it's especially relevant to my life. I'm not a simple creature like an earthworm, so who cares about reductive shit like my chromosomes? My brain is far more important.

I have absolutely no idea what to make of your friend. Can't tell if they're being a special snowflake Tumblrite, or just a pussy about transitioning.

you can get people born with female bodies and XY chromosomes and people born with male bodies and XX chromosomes though
lrn2intersex

sex =/= chromosomes
sex = phenotype expression of a variety of chromosomal, genetic and environmental factors

Male seahorses don't really give birth, that's a misconception.
Basically they have a pouch like a kangaroo that the female lays her eggs in.

You mean biological males with child-bearing hips and biological females with five-o-clock shadow?

Has there been a case of an XX being able to impregnate, or an XY being able to be impregnated?

Probably because he's a faggot who's too pussy to just go ahead and be faggy while still being cishet, so he has to hide behind and delegitimise a medical condition.

Second.

>With the push to broaden the definitions beyond the confines of chromosomes,
Not to be a pedantic little shit, but I'm gonna be a pedantic little shit and point out that gender was never defined by chromosomes. Ever.
By the time humanity was even aware that chromosome existed, we were also aware of things like androgen insensitivity syndrome and other conditions that just totally override your sex chromosomes.
