The types you are referring to are non-consensual and are legally considered rape. That is a crime. Consensual sexual relationships between adults is not a crime, be it heterosexual or homosexual or between transgendered or intersex people. Stop comparing homosexuality to crimes because it's extremely offensive, not to mention really, really stupid.
Precisely. I do not understand why people's brains cannot wrap themselves around the idea of consensual sex between adults being okay.
