ItsTooEarly Accepting "enforced hospitality" is odd, it's a cup of tea, not an AK47.
I have understood the video. I don't think your use of it as a comparison stands.
As a guest, you are there to be appeased and to appease, hence "me casa su casa" is a metaphor for welcome, not literal. It's a polite act, a necessary performance, a way of oiling the wheels of social intercourse.
Your parallel to the cup of tea in the video is entirely misjudged. While the cup of tea works as a way of re-thinking consent about sex, it does not work as a way of thinking about tea in the domestic sphere, i.e. this thread.
An example of this would be that the video does not invite the non-tea drinker to consider cultural norms about accepting some tea, and that's because it's about sex, not tea. It does not say that in some cultures you must expect to be offered tea and to accept it as a politeness , because the video is about sex, not tea.
Upthread, points have been made about asking for a glass of water as a way of signalling acceptance of hospitality, but on terms that that satisfy the host's desire to place, with the guest's desire not to have tea.
The video, which is about sex, not tea, does not address this, and quite rightly. No, is no.
This is why your reference to this video has no application to the thread.
