Looking at it from different perspectives, Oregon allows illegal immigrants to receive drivers licenses. While that seems trivial it also allows them to open bank accounts, apply for loans, and live under the guise of being legal citizens when it's convenient but still get the lovely federal assistance for things like free education with no compulsory citizenship or other contribution to the US.
Now, 'guys' are having babies. I'm not familiar with much of Oregon's law but mixing up sex roles could effect things such as insurance and health care.
My problem is with Oregon declaring a viable woman to be a man. Sure, she's a masculine figure, but her sex is still a woman.
Again, gender= self identity, what you 'feel' like you are. Sex= what organs you have. You can't "make" a penis any more than you can make a vagina. Thus, turning a penis inside and using the nerves in the head to make a sensitive area similar to a clitoris does not a woman make. Growing facial hair, and having a swollen clitoris doesn't make a man.
Then again, maybe I'm old fashioned.
