Believing in dull, barren, soul-dead Scientific Materialism is everyone's right, but

66. First, you did not answer the question. Second, what 'science' was the 'disease' theory based on?

What 'evidence' did they use? Answer, none, they elevated assumption to the state of fact, gnawed that bone hard for generations and when people were walking on the moon, these folks still held that gay people had a disease.
What qualified these beliefs as 'science'? The degrees of the nuts who promoted them? Sorry, but I grew up hearing 'medicine' and 'religion' spout the same obviously false bullshit about gay people. The 'science' was just religion in a lab coat. Mumbo jumbo. Fakery. Magical thinking posing as actual established fact.
So 'science' stopped teaching that gays are diseased about the same time Mormons stopped teaching that black people carry the curse of Ham, early 1970s. Both teachings were based on nonsense, dogma, bigotry and no evidence at all.
I guess that's how religion works too, when a belief becomes untenable in the face of fact and reason, jettison it and take up the current modes.
A group of professions that thought gay was a disease in 1973 has no standing to whine about other people holding silly false beliefs. Those professions harmed others by taking their crappy beliefs into practice in the name of science. Their concern should be that they never commit such atrocities out of ego and assumption again.
