The right to mis-define oneself

[henryp]

So, I think where some of us are getting tripped up, is that as "atheists" many of us are all about the whole measurable fact department. So when you say "She's not in the most strictly biological...", that's how many of us define male/female.  Strictly biological.  
And the rest, to some of us, is immaterial.  I think it's, interestingly, associated with the movement to remove gender stereotypes.  If this were 1950, when women were still in the little box of how they were supposed to behave, then it'd probably be a lot easier to accept.

Instead, we have a culture that rightly believes a man or woman can do whatever they want, and it doesn't make them less of a man or woman.  Femininity and masculinity are no longer factors.  Sex with the opposite sex isn't a factor.  Liking musicals, being in touch with your feelings, punching people for a living.  It's all wide open.  A woman can be anything.  A man can be anything.  

So now we have a man who says "I identify as a woman."  But there is no longer a "woman" identity in some of our minds.  So it's like the Transgender stuff is lagging 20 years behind our current views.  For some of us, the labels of "Man" and "Woman" only exist as strictly biological identifiers.

We've addressed this already. It has nothing to do with interests, stereotypes, sexism or what society perceives to be male or female. This is rooted in brain structure and chemistry.

Sex is strictly biological. But we are talking about gender identity, a much more complex issue. A transgendered person's brain is bombarding them with the information that they are of the opposite sex than that assigned to them at birth. It isn't about whims. Gender dysphoria is a factual mental condition.

What you are vs. what you think you are.  But you think that what you think you are is what you are.  I'll certainly read more about it going forward.  Just intuitively, I don't get it yet.
