It's funny how people say that racism is not like gender discrimination because gender is determined by different genetics.
Of course, they forget that the same arguments were used to justify racism.
The genome is like a long and not completely understood book, and like any long and not completely understood book, loudmouthed fundamentalists can cobble half-truths from its contents to support hateful dogma.
Go ahead. Genome away. Tell me what makes a perfect man or a woman. Tell me what makes a perfect human. Really? ;) Riiiiight.
