But to prove that, we don't need to know that a couple particualar gay guys
lack elder brothers - we need data on a whole lot of gay and straight men.
It's of course possible that the study was based on false or biased data, but
as said I see no particular reason to assume so.

I can't see any a priori reason why the causes of male homosexuality should
necessarily the same as those of female homosexuality. The article asserted
that there is no correlation between a woman's sexual orientation and the
number of her elder siblings of either gender.
