Obviously, the passage of a same-sex marriage law in New York was a great step. The most interesting, because as impressive as it is simple, is the change of mind of Senator Grisanti, a Republican who campaigned against same-sex marriage for his election:
I cannot deny a person, a human being, a taxpayer, a worker, the people of my district and across this state, the State of New York, and those people who make this the great state that it is the same rights that I have with my wife.That's so simple, and that's so obvious. Anyway.
If you are interested in the issue, you probably want to watch this Ted Talk by Northwestern Professor Alice Dregen. The presentation is amazing. Basically, the bottom line is that the gender classification between male and female is a convention, not a given. You can see this with "intersex" people. People with androgen insensitivity syndrom have XY chromosomes but do not develop outside testicles by lack of testosterone receptors. Who should they marry? Should they be able to adopt? Some people with congenital adrenal hyperplasia have XX chromosomes but overproduce male hormones which create masculanized genitals. Can s/he marry his/her girlfriend?
In any case, the strong conclusion of Dregen's talk is food-for-thought
Nature does not draw the line for us, between male or female, or between male and interesex and female. We actually draw that line
