It's not pedantry, it's the heart of the issue. I don't think anybody is criticising others for not having sex or saying people that don't feel sexual desire aren't real, as you seem to be suggesting upthread.
What's criticised is giving yourself a label, then telling everyone about it and claiming to be oppressed because of the label you made up.
Absolutely this. It’s this ridiculous label and the claims of oppression and discrimination that go with it. As well as the torturous logic of those claims.
At heart, is the issue that lots of people, for all sorts of reasons, at various points in their lives, do not experience much or any sexual desire. These fluctuating and context-dependent aspects of sexual
attraction/desire/interest are ordinary and standard features of the human condition.
Insisting that this is some kind of essential
core of your identity is ridiculous. As is telling everyone about your lack of sexual
desire.
It simply isn’t relevant in the vast majority of situations - unless you’re looking start a relationship with someone no one cares what your levels of sexual attraction or desire are. They might care when you insist on turning the conversation to it, but more because it’s just as weird and inappropriate to be announcing to your colleagues ‘I’m not interested in sex’ and it would be to announce ‘I love being spanked with a first generation Wii remote’.
That’s not ‘closeting’ anyone. It’s that, for all practicable purposes, to your colleagues and other acquaintances you are simply single or in a relationship. They don’t want to know whether you are having sex in either situation.
Other than this weird desire to capture anything and everything in a letter and a stripe on an ever expanding flag, the concept of ‘asexuality’ is just not that important.
