About to get this thread detached, but I wanted to take a stab at answering your good faith question!

My understanding is there are two groups here, and depending on where you live one or the other of them will get you into hot water:

Group A-1 believes:

1. Gendered identities are a social construct, meaning your gender is dictated by how you are perceived socially

2. Gendered expression is good

3. Every person should have equal access to all social structures

4. Therefore every person should be allowed to access whichever gender identity they prefer

5. Because gender is socially constructed, this requires your social group to be on board with assisting in the social construction of your gender identity (using the correct pronouns, etc)

6. Therefore it's wrong, and anti-freedom to deny someone's gender identity.

7. Sex is an outdated concept, existing for historical reasons to prevent #4, and in the rare cases it might be medically or sexually relevant should be replaced by a "basket of physical characteristics"... hormone levels, genital structure, etc, as the individual situation may require

Group A-2 believes:

1. Most of what A-1 believes, except:

2. Gendered expression is not good, because it is a conduit
for misogyny

3. But it's inescapable in today's society

4. And people expressing gender outside of their social assignments helps break that down

Group B-1 believes:

1. Sex is still a relevant concept medically

2. Sex is still a relevant concept because some peoples' sexualities are tied to sex not gender identity

3. Sex is still a relevant concept for understanding patriarchy, and it's counterproductive to the goals of women's liberation to try to dismantle sex groups before dismantling patriarchy.

4. Encouraging transitioning as a solution to #3 is bad, because it reifies gender roles.

5. Sex is not malleable

6. Forcing others to reify your gender identity impinges on their right to build social groups around sex identities (for reasons like #2 and #3)

7. Gendered expression is not good, because it is a conduit for misogyny

8. People should express themselves however they like, but this has nothing to do with sex or "gender"

9. Gender doesn't really exist

Group B-2 believes:

1. Most of what A-2 believes, except:

2. Gendered expression is good, because tradition

3. Patriarchy is about as powerful as Matriarchy so it is not important to dismantle

4. Encouraging transitioning is bad, because tradition

IMO this debate can rage on forever because whichever side you're on, you can pick and choose from the -1 and -2 variants to concoct an evil version of either perspective.

Also, I truly love all three of: A-1, A-2, and B-1 and I think all three of them hold very important kernels of truth. As of 2022 I can't see how they could be reconciled but it one of my greatest desires that one day they could! Save us Gen Z! I don't think I'm supposed to support B-1 in public though, so I mostly don't. And from your question I think you agree that B-1 is problematic? If I had to pick just one for society I'd pick A-2, but I think it misses a lot of the picture that B-1 is trying to hold on to.

Anyway, I thought this breakdown might help answer your question? Did it?
