Would gay activists’ heads explode at the contradiction of being pro-choice when parents can chose to have only straight children?

No, but they sure would press for an exception to "choice" in that case...any dr who aborted a homosexual fetus (ahem) would be guilty of a hate crime...and compared to Joseph Mengele. (And no, I didn't violate Godwin's law: the writer of the article did so)

I suppose you're right. The test would be outlawed just as India outlawed using ultrasound for detecting the sex of an unborn child because too many parents were deciding to abort girls.
