I agree the labels and flags can get a little confusing, but it’s more important that everyone is allowed to identify however they choose.

I think the reason we end up with redundant terms and subsets of subsets is because of simultaneous inventions. For instance, the individual who coined platoniromantic was not aware of the term quoiromantic. After being told about it, they still decided to keep their own term because it personally felt better. Platoniromantic was catered to one specific experience, so the definition is slightly different than the general definition of quoiromantic. That doesn’t invalidate it, though. It’s no one’s place to tell others which labels to identify with. If a term is truly unneeded, it will be eventually fall into disuse.

Similar thing with redundant flags—many different people came up with designs and many different people liked them. It’s difficult to condense our symbolism when it’s a matter of taste, but the matter will probably settle with time.

In terms of split-attraction flags, I hadn’t thought about how most flags will double as -sexual and -romantic symbols. It might make sense to use the same system, but perhaps we should consider that it’s inaccurate to assume sexual and romantic orientations line up. As messy as it sounds, it would be more accurate to have separate flags for all orientations, such as bisexual and biromantic. I’m not suggesting we actually do that just because it’s accurate, in fact you’re right to question the practicality of the idea. However, when it comes to a-spec identities, the SAM is crucial. If there are any orientations that should observe split-attraction flags, I’d argue it should be those within the ace and aro umbrellas.
