@ 49 - "If someone genuinely perceives you to be feminine, masculine, both, or neither, who are you to tell them they're perception is wrong?"
Seandr, you're way off base here. Gender is physiological. There are physical differences
in the brain that determine gender. And medical science has found that trans* people's self-identified gender is reflective of the structure of their brains. Here's some of the current research:
“These data suggest a pattern (in male to female transsexuals) of activation away from the biological sex, occupying an intermediate position with predominantly female-like features”
The white matter in the brains of female-to-male transsexuals who have not yet begun hormone therapy mirrors the white matter in male brains rather than female brains. "It's the first time it has been shown that the brains of female-to-male transsexual people are masculinised," Guillamon says.
And then there’s this:
From the abstract:
”Results revealed that regional gray matter variation in MTF transsexuals is more similar to the pattern found in men than in women. However, MTF transsexuals show a significantly larger volume of regional gray matter in the right putamen compared to men. These findings provide new evidence that transsexualism is associated with distinct cerebral pattern, which supports the assumption that brain anatomy plays a role in gender identity.”
From the results:
“For each of 22 significantly different regions (twelve within the right hemisphere and ten within the left hemisphere), cluster-specific box plots were generated to illustrate the magnitude and direction of gray matter volume differences between groups (see supplement 1 and 2). Altogether, females had the largest gray matter volumes in all but two significant clusters, which were located in the left and right putamen. Here, MTF transsexuals had the largest gray matter volumes (see Fig. 1). For the remaining clusters, MTF transsexuals had the smallest gray matter volumes, but their data spectrum largely overlapped with that of males.”
In other words, current research shows that gender is not a binary, that physical sex and physical gender do not always align, and that trans* people's perceptions of themselves are correct. So please, don't insist on disregarding the gender identities of others. In addition to being unnecessarily unkind, doing so is also wrongheaded.
