R0wantrees That doc blew my mind. Any number of things to comment on, but here are a few.
The producer, Della, talked like a man throughout. I don't mean the pitch of her voice, which was low but within normal female range—I mean her pragmatic behaviour. She directed the conversation to an excessive degree, and then, when the two men joined in, she talked over them, as only a man would do. In appearance, she also reminded me of John Cleese as Dinsdale Piranha's ladyfriend, but this may be in part an effect of the change in dress codes since then. They were all dressed and coiffed very conventionally, but this was 1973. And the "married" TW saying her husband was happiest when she was in the kitchen (as you pointed out) was very 1973.
Della was also, as you say, confused about the labels she threw around, then decided weren't important when corrected. And there was no real enlightenment as to why they thought they were women. One of the other three TW said she thought she had chosen to be female, only for Della, typically, to correct this, asserting that they just were women, it wasn't a matter of choice. Rachel said she regarded being a woman as a status symbol (as you say), but Jan seemed to admit she was biologically male (talking about how embarrassing it would be to be assigned to a male ward!). Clearly they were all worried about "performing" the female rôle in a convincing way, emphasising how they didn't want to be like drag queens—while never questioning what the female rôle was (is) or why it was (is) what it was (is). Doubtless the "married" TW thought women have the best deal because she was married to someone who supported her while she didn't have to work and obviously no kids to take care of.The discussion about legal standing at the time was the most informative part, in factual terms.
The spookiest bit was Della saying that we are all intersex, that transsexuals are 'the tip of the iceberg', and that in the act of love we try to consume and become the beloved. I was reminded that this is a view the Roman Epicurean poet Lucretius shows vividly is absurd and incoherent. I'm with him. Also, it's also plain weird. Why do you want to become them, rather than sharing pleasure and intimacy? What happens to the other person? Don't they get to play?
