Like the article says, how do you prove Asexuality? (Not sure why my iPhone insists that word must be capitalised.) It’s proving the absence of a thing. Or a concept.
I feel like this is something that isn’t intended to be used to catch people who are ace. I think it’s something they’ll tack onto other charges. Like making something up. Unmarried? We can also say he’s an ace and keep him locked up longer. Doesn’t make sense. Don’t have to. Dictators and all that.
