Disclaimer: This got really long. Oops? I'll put a tl;dr at the end in case you don't wanna read the whole thing.
I think the problem comes from -- and correct me if I'm wrong -- the tendency of many aros and non-aros alike to use the word "queerplatonic" as meaning "like a romantic relationship without the romance" or a "soft romo" or "romance light" so to speak, instead of using it as I believe it was originally coined, to refer to bonds of friendship that are different from what many romantics see as friendship. Because we can pretty much agree that many romantics view friendship as a far more casual, less exclusive or less important thing than many aromantics do (obviously I'm generalizing here, but if we're looking at it from a broad perspective).
We have words like "queerplatonic" and "squish" to emphasize that platonic feelings are of value and importance and that platonic bonds can be very strong and deep. It's to show romantics that when we think of friendship, often we're thinking of something stronger than the more casual acquaintanceship that many romantics consider friendship. Because we all feel stronger bonds to some people than we do others, no matter what kind of bonds those may be, and words like "queerplatonic" establish that strong bonds don't have to be romantic, that there isn't an invisible ceiling between friendship and romance, that they are two separate things.
And "queerplatonic" shouldn't even be reserved for partnerships. Who ever said you had to be someone's partner to have strong platonic feelings for them that don't fit the mold of what romantics call friendship? We all define words differently, and I personally define queerplatonic as really strong platonic feelings/love/attraction that's different from casual friendship. That's just me. But regardless of how we define it as individuals we can't confine it to this box of being basically dating without the romance, because that's really ignoring the vast spectrum of different types of bonds people can have and the forms they can take.
The problem arises when we start to use these words not to describe something unique but to instead defend ourselves by trying to make ourselves seem more "normal" to romantics. It is not our job to conflate our experience with theirs in order to make them more comfortable with our existence. None of this "I'm aromantic, but I can still form queerplatonic relationships which is like dating without romance!" Being aromantic is beautiful, not something that has to be made up for by trying to act like we're anything like romantics. Let's change that to "I'm aromantic, and sometimes I form really strong platonic bonds with people that are unlike casual friendship. Sometimes we call that 'queerplatonic.'"
tl;dr yeah, in some ways we dig ourselves into a hole by using these words, but not because of the words themselves, but because of the way we use them to conflate our experiences with those of romantics, instead of using them to define something all our own. We can combat unconscious amatonormativity by embracing our experiences instead of trying to make them seem worthy by comparing them to romantic ones.
Because being aromantic is nothing to apologize for.
EDIT: For some more reading about amatonormativity and queerplatonic friendship, this article sums it up pretty well, and is where I got a lot of my inspiration from for all of the above.
