Everyone's favorite science guy debuted his new show, Bill Nye Saves the World, on Netflix last week. The show has the specific purpose of debunking anti-scientific claims. Whether that be misconceptions about climate change, vaccinations, or sexuality, for example.
If you look at the scientific evidence, it's pretty clear that homosexuality is natural and observable in almost every animal on the planet. No, it's not a choice. And no, gay conversion therapy won't magically make someone heterosexual. The Human Rights Campaign states that the practice can lead to "depression, anxiety, drug use, homelessness, and suicide."
Bill Nye addressed the issue in an episode of the show, pointing out how ludicrous the argument for conversion therapy is by turning people into different flavors of ice cream.
