If Giraffes were homosexual they would have long ago become extinct.

But I remember Proximo complaining about queer giraffes in the movie Gladiator.

Aberrent sexual behaviour such as homosexuality does exist in animals. It's very rare though.

As for the "queer giraffes" in Gladiator - that's probably nothing more than a snide euphemism for the known fact that its very hard to breed many large African animals in captivity.
