I saw an argument about transgenders identity on here and felt it would be a good idea to explain the difference about changing your sex to changing your gender.
True you can not change your sex.
The definition of sex is as follows.
Sex refers to a set of biological attributes in humans and animals. It is primarily associated with physical and physiological features including chromosomes, gene expression, hormone levels and function, and reproductive/sexual anatomy. Sex is usually categorized as female or male but there is variation in the biological attributes that comprise sex and how those attributes are expressed.
These features cannot be changed.
But the argument isn't about changing their sex. It's changing gender.
Here is the description of gender.
Gender refers to the socially constructed roles, behaviours, expressions and identities of girls, women, boys, men, and gender diverse people. It influences how people perceive themselves and each other, how they act and interact, and the distribution of power and resources in society. Gender identity is not confined to a binary (girl/woman, boy/man) nor is it static; it exists along a continuum and can change over time. There is considerable diversity in how individuals and groups understand, experience and express gender through the roles they take on, the expectations placed on them, relations with others and the complex ways that gender is institutionalized in society.
So yes a person can change gender. Gender is how society and oneself acts and perceives or identifies themselves as.
So the argument that it's impossible for one to change their gender is incorrect. Anyone can change their gender.
Sex is biological and is not interchangeable.
Gender us how a person sees themselves.
If a man decides he wants to be female. He will always be male biologically but he percieves himself as a female and he has changed his gender to female because he perceives himself as one.
That is why they identify as transgender and not transsexuals.
