I love when ignorant jackasses try and say this shit because then I get to tout out one of my favorite natural phenomena: The Whiptail Lizard. Several entire species of lesbian lizards that have sexual interaction with each other to trigger self-fertilization.
So, no. There are actually multiple species that are entirely gay that are doing just fine! Teiidae is just one example. Any species capable of parthenogenesis, which includes insects, invertebrates, fish, amphibians, reptiles, and some birds, could sustain an entirely gay population, and some already do.
There are also plenty of species that engage in same-sex mating more often than male-female mating that are doing absolutely fine. Like giraffes, most cetaceans, most primates, and most damsel and dragonflies.
