The problem is girls being forced to choose between holding in their pee and sharing a bathroom with cis boys
So in other words you posted something that has absolutely nothing to do about the thread title or even OP material.
I at least assumed you posted something germane to the topic. That, I think, was my mistake.
Your complaints about poor civil engineering aside, wherein the organization of a single-gender bathroom to prevent these problems is possible, but not quite what those used to designing bathrooms in the US expect, say nothing about whether trans people ought to have some right to transition.
If you wanted to actually be useful, you would pull up the floor plan of those bathrooms and design a solution rather than designing new ways to complain about the failures of those who do things poorly as an excuse to just not do things.
Why don't you think it's related to the OP? We're talking gender norms here.
No, the topic is quite clearly "transgender".
If you wanted to discuss "gender norms" that's its own topic
That is not about transgender. That is about post-gender bathrooms, and the issues created by bad civil engineering.
It says nothing as to whether trans people deserve rights. It only says that a number of civil engineers don't deserve the right to remain civil engineers, or need to go back to school.
The documentary is about contemporary liberals inability to define what a woman is. It's in the title of the documentary. So it's absolutely about gender norms. It's the main focus.
Transgenderism is brought up is because (my interpretation) because it highlights a paradox in the progressive narrative.
The postmodern dichotomy states that men and women are the same, and that we only behave differently because how how we have been socialised. If that's true, then what's up with the transgendered? Clearly, to those who are trans, there's different rules for women and men? To them, it's clearly a big deal what gender we are. To the point where they're willing to undergo extensive surgery and are willing to deal with the trauma of taking powerful sex hormones to change those hormones. If gender is just a construct, why go through (what must be a traumatic) nightmare to correct it?
The denial of gender differences of behaviour is like an ongoing bizarre huge conspiracy within the left. I understand where it came from. The evolution of this idea makes perfect sense. What doesn't make sense his how this idea survived into and out of the 1980'ies and keeps going. We have had solid scientific evidence proving behavioural gender differences from before post modern gender theory even became a thing.
In the 1970'ies, in the name of feminism, and introducing women into the workplace on equal footing of men we wanted to believe men and women behaved the same. For some reason this was considered an essential truth if we wanted workplace gender equality. It's not. Now we know it. But now women are a common sight on every level in the workforce. Women are obviously as professionally capable of men without us having to postulate that they behave the same. But we keep going with making this claim.
I suspect it's just the sunk cost fallacy. The left has been saying so long that gender is just a construct that we're hesitant to admit that it's not. It's unfortunately also become an ideological divide. Where claiming gendered behavioral differences is associated with conservatism. Which further makes it harder, within the left, to admit we might have made a mistake.
My position is that claiming that gender is just a construct is an anti-feminist position. Because... by necessity we will need to decide that the correct norm is either male or female, and force the other gender to act the gender they're not, and pretend we're treating everybody fairly. It also makes it impossible to acknowledge gender specific struggles and talk about them. It robs us of the ability to create norms and traditions that help men and women function better together in the work place. I'd argue that those traditions and norms have already been developed and are in full effect. But we're not acknowledging them. These are tacit arrangements that young people starting their careers just have to pick up along the way somehow.
I think it's high time, we in the left, stop putting up with being a part of this gender-is-just-a-construct conspiracy. It's helping nobody any longer. I think it's doubtful it ever helped anyone.
