I'll steelman her POV because it seems people are (rightly) confused.

Asexuals are requesting a day of recognition for what she sees as a negative-identity. Keep in mind, conservatives are often meritocratic.

It's like if there were a day for "coffee refrainers", for everyone who doesn't like drinking coffee. I'm sure if someone dunked on that day and the coffee refrainers, it'd all be in good spirits.

But if someone dunked on asexuality, I'm sure it'd cause a lot of upset and defensive argument, which implies more "merit" to asexuality.

While progressives can go "who cares, just leave em be", conservatives see all "non-deserved" attention as an affront to meritocracy, that needs to be squashed.
