@IceHurricane Note the presence of the word "just" in three of those points.
Whenever I talk to people, I make a point of leaving it out. Nobody ever just wants something. Nobody ever just is something. People are far too complicated to box in like that. It's a word intended to compartmentalize the subject into something manageable and comprehensible to the user, often at the cost of any real meaning. "Just" is a tool used to create and implement the Straw Man Fallacy. It's a way of saying "that's all they are," or "that's all they do." Perhaps something like, "that's all you need to know about them." It is a tool to simplify the complicated, and for that it's often misused. Certainly not just in dismissing aromanticism.
When someone tells you you're just afraid of commitment, keep that in mind. I'll actually admit I am afraid of commitment, but I am absolutely not JUST afraid of it.
There's a whole other argument to be made about the use of the word "can't" but I feel it's less relevant here.
