Seems like an odd claim:
Senior Labour figures have become embroiled in a bizarre gender policy row over whether male giraffes are naturally gay.
The controversy began when Dawn Butler, Labour’s shadow secretary for women and equalities, gave a speech at the Pink News awards defending the teaching of lesbian, gay, bisexual and transgender issues in schools.
She cited giraffes’ gay behaviour as evidence of how ridiculous the concept was that children could be taught to be gay through lessons on LGBT issues.
I grasp the various arguments about how any why gay exists. The gene, just as one example of such an argument, is beneficial in other formats or circumstances, thus it persists generation to generation even if it is not beneficial to the generation of descendants of the individual. And all that.
But I really do struggle to see how an entire population can be 90% gay from generation to generation. Seems most unlikely as an evolutionary outcome.
