You sagely do what so few do, especially when it comes to this particular debate. You idnetify the larger intellectual challenge of well-meaning but dogmatic thinking, which can be found in many segments of our culture. That said, the idea that issues of identity, sexuality, and pretty much everything else, are a blend of social and biological influences should not be desparaged, as you seem to. In fact, your own objections point to MY conclusion!
You are upset by the notion that gender and race are social (presumambly because you think they are biological), but refuse to acknowlewdge anything biologically determined about homosexuality (presumably because you think it is social). So, you actually admit that both forces are at work, you just don't like how some people weight the influences. Well and good, but don't pretend that even you see them as being both real and active.
In terms of teaching Creationism is school, I favor it, AS LONG AS IT IS TAUGHT IN SOCIAL STUDIES, HISTORY OF RELIGION OR CONTEMPORARY AMERICAN CIVILIZATION. It is a real belief and actually is an approach which raises valuable issues, BUT IT"S NOT SCIENCE.
