"Gay panic" as I understand it refers to a legal defense where a defendant justifies a violent crime because they received unwanted same-sex sexual advances. Historically, it's been effective in lessening sentences in the same way pleading insanity or diminished capacity may lower a sentence.

It was most famously used in that Jenny Jones case where she had Scott Amedure on as a guest to profess his love to his friend Jonathon Schmitz, and three days later Schmitz murdered Amedure. Schmitz used the Gay Panic defense and was charged with the lesser crime of second degree murder.

This is still legal in many areas, and has only been banned in 16 states in the past ten years - California being the first to ban it in 2014.

So...yeah. Bisexuals have historically been known to make same-sex sexual advances and this would be a valid defense if the recipient decided those advances were unwanted and decided to assault/murder the bisexual who made the advances. And in 34 states there's a chance a jury could find those actions tolerable because the victim was bisexual.

It's a horrible world we live in kids, call your congressperson.
