So, I think this is actually evidence simply that behaviors or accomplishments viewed as highly unusual (either positive or negative) are often ascribed to a physical basis, whereas anything perceived as being in the normal range of human behavior in the culture is seen simply as the individual's choice or self expression.
I'm not sure about that. The being gay/trans is inborn thing was concocted to better fit the mold generated by the blacks' and women's rights movement which relied on arguing that it's wrong to "discriminate" against people for something that's not their fault.
Do you have evidence that it is or is not inherent? For evidence of gayness being inborn there is the digit ratio where if you scroll down to sexual orientation you'll see that lesbians have a lower average digit ratio. This has been suggested to be affected by androgens like testosterone while in the uterus. This is evidence that sexuality is inborn. If true the obvious parallel is that a person can no more change their sexuality than choose to have one finger grow more than the other.
Edit: Having just looked around, It seems there is a long list of diffe...
What is something you used to believe, preferably something concrete with direct or implied predictions, that you now know was dead wrong. Was your belief rational given what you knew and could know back then, or was it irrational, and why?
Edit: I feel like some of these are getting a bit glib and political. Please try to explain what false assumptions or biases were underlying your beliefs - be introspective - this is LW after all.
