Nobody is ‘born that way,’ gay historians say

[TJ in Oregon]

I don't really understand the point this author is trying to make.  He argues that people aren't born with a sexual orientation, yet he acknowledges that sexual orientation is something that is beyond the individual's control.  Even if nobody is "born that way," why does the social construct theory become the default position?

He's arguing (I think) that the entire idea of there being such a category of person as "sexual orientation" is itself a social construct.
