Gay as as…giraffe

In the long debate on whether homosexuality is “natural”, “normal”, etc. it can be a useful to have these examples on animal behavior as part of campaign argumentation.

We nevertheless suggest to do more research and provide quotes from trusted institutions. GSN is arguably NOT a trusted source to homophobes. And the much cited https://en.wikipedia.org/wiki/Bruce_Bagemihl is often the only reference on the subject. It has to be noted though that although he is an academic, he is also a gay advocate, which minimizes his credibility with the public.

Also, at the end of the day: since when do animals provide justification for human behavior???
