Bullshit. LOL every time one of you try to make an assumption about what the field of science believes, you can bet the complete opposite is true.
"Our phylogenetically informed analyses testing for associations between same-sex sexual behaviour and other species characteristics suggest that it may play an adaptive role in maintaining social relationships and mitigating conflict."
There is still no consensus on the factors favouring the evolution of same-sex sexual behaviour in mammals. This study presents evidence that it is a widespread behaviour that has evolved repeatedly in mammals, and that may play an adaptive role in bonding and conflict resolution.

"Some scientists argue that most instances of same-sex sexual behavior are not costly, but instead adaptive—that is, same-sex sexual behavior provides some benefit that outweighs its costs. These could be benefits to survival such as social bonding, stress relief, and community maintenance."
Scientists have long known that animals engage in sexual behavior with individuals of the same sex.
