That bisexuality paper was rampant with biphobia and transphobia.

The entire premise is:
We think bi men are liars. Let’s test this by seeing if penis is or is not aroused when seeing another penis and/or vulva in an erotic way

The authors decided to translate this to:

Penis = man
Vulva = woman

Not sure how many times it needs to be said, but gender does NOT equal the genitalia one does or does not have.

The authors also buy into the gender & sex binaries and that bisexual men only exist within and are attracted to those within this binary.

MANY bisexual people would disagree with this.

Also, the binary is fake! Gender is a spectrum. Sex is a spectrum. It’s 2020 Google is free!

There are many other gender, sex, and sexuality scientists who have articulated that last bit much better than I ever could. Again, Google is free. Please use it.

Take home messages:
- that paper is disgusting and needs to be retracted ASAP
- every author deserves unending condemnation
- someone else’s sexuality has NEVER been and will NEVER be any of your business!
