"The chief imperative in cases like mine was to show no doubt as to the gender of the child in question. You did not tell the parents of a newborn, "Your baby is a hermaphrodite." Instead, you said, "Your daughter was born with a clitoris that is a little larger than a normal girl's. We'll need to do surgery to make it the right size." [Dr.] Luce felt that parents weren't able to cope with an ambiguous gender assignment. You had to tell them if they had a boy or a girl. Which meant that, before you said anything, you had to be sure what the prevailing gender was." from the novel "Middlesex" by Jeffery Eugenides
We human beings like things to be well-sorted. We are not comfortable with ambiguity and prefer things to be black and white. Perhaps this is why the trans and gender-queer community makes quite a number of heteros and homos shake in their boots [present company not included].
The T in LGBT reminds us that sexuality is a bit messy. It isn't easily categorized. I think this is a good thing. If God created nature with such diversity and variety then why do we assume that our sexuality does not follow suit? I believe the trans community is a great gift to all of us. I hope we will listen to what they have to teach us. I still have a great deal to learn on this subject...so if there are any trans people out there who are reading my blog...please consider writing a short article. I'd be honored to publish it.
