The idea that pansexuality is intrinsically biphobic is ridiculous.
One of the things that pansexuality has done is emphasize that gender is not binary.
It has never said that a bisexual person is relegated to Binary interest.
Any it has simply bolstered the acceptance of trans and non-binary individuals.
Over time people have become more accepting and identify as bisexual or pansexual, but the idea that a sexual orientation developed to revolutionize the acceptance of non-binary and trans people must meet biphobic it’s just ignorant.
It took me a long time myself to be willing to identify as pansexual because I already valued the idea trans and non-binary people whoever they were. I’m an asexual who behaves pansexually. I identified as bisexual until my partner introduced asexuality to me and I realized I was ace. I only claim sexuality as a specific political statement. A lot of people that are bi still stick to the idea that gender is binary because they focus on genitalia. For me identifying with pansexual what’s the political and activist move challenging transphobia.
There is a super harmful article by bisexuality.org that is reinforcing myths about sexuality furthering the misunderstood of it political nature. A quick Google search shows more articles of the same.
That’s one of the reasons why it is important that the is invisible sexualities have visibility and education surrounding them. Because we keep propagating harmful misinformation about the creation of these ideas and labels pitting ourselves against each other in fear of being erased or misunderstood by cishet folks or GRSM people who don’t take time to learn something outside of their own identity.
