donald trump is following the ultra-conservative ultra-christian right agenda and attacking gender-sexual identity.
victor hugo says in "les miserables", with the character, father bien venu: i have my life, and my neighbor has his life, it is the one his god has given him.
psychology of sex and gender says there are 7-gender identities: heterosexual, homosexual, inter-sexed, bisexual, transsexual, a-sexual, and omni-sexual; there are three biological sexual identities: male, female, and inter-sexed; plus, there is a sexual-orientation for each gender-identity, so heterosexual, homosexual, transsexual, bisexual, intersexed, a sexual and omnisexual. do the math: 7X3X7= 147 types of people, each with their own personality-identity.
perhaps it is the ultra-christian influence, but defining every one by their genitalia might be a problem; this is why trump wants to use birth records to identify people. when i was born, my parents named me after my genitalia, long before i had a personality develop of my own. being an adult, i believe i have the right to decide my own identity, and to have the government recognize it.
