Yeah, it seems a long way from the original
""Dress however you please, Call yourself whatever you like. Sleep with any consenting adult who'll have you. Live your best life in peace and security. But force women out of their jobs for stating that sex is real?"
tweet.
That was basically "live and let live unless it actively hurts others"
Now it's more like "let's make fun of anyone who sits slightly outside the norm, despite their identity having no actual negative impact on me or anyone else"
I appreciate the point posters have made about the possible link between using asexuality to push the normalisation of potential inadvertent sterilisation/loss of sexual feeling etc as a possible side-effect of transitioning, but tbh it all sounds a bit 'bogey man.'
Firstly, even if there are these devious idealogues deliberately co-opting asexuality to push an agenda from the shadows, that doesn't change the fact that asexual people do exist. A minority using asexuals' legitimate identify for inappropriate purposes isn't a reason to mock the majority.
Also, JKR didn't specify anything about that. We all know she is able to explain herself well if she wishes, and if she wanted to make a salient point with relevant proof she absolutely could have, but it reads more as if she just wanted to mock the concept of asexuality, which seems unnecessary, if she just thinks it's ridiculous and not actively harmful.
Lots of things might seem a bit silly or pointless if they aren't relevant to you, but if you start getting annoyed about all of them surely it's just a bit exhausting and unnecessary?
