In case you haven't figured it out, it's one of those "lgbts can't compare their struggle for equality to that of the African-American civil rights struggle because you can hide your sexual orientation but not your race and the Bible says that homosexuality is a sin" pieces that always serves to mentally exhaust me for its lack of basic logic and desire to ignore the empathy that one group who has dealt with inequality should have for another group having the same problems.
Rather than go over it, I would rather show the response I wrote. It's short and to the point:
Rick, whether someone can or cannot hide their homosexuality is irrelevant. You forget that some blacks tried to pass as white. Also, please bear in mind that before you refer to the Bible, it was the Bible which was used to justify slavery and segregation. Lastly, your diatribe forgets the basic existence of black lgbts - which I am one. Really there is no difference between "gay rights" and "civil rights" because they are all human rights. And when a group of people are denied their due, whether it be on the basis of discrimination on the basis of race, religion, or sexual orientation, we all suffer.
