Not even just aro or ace. You can be homoromantic heterosexual or heteroromantic homosexual or any other combination. While it’s unusual for people to have conflicting sexual and romantic orientations, it does happen.

Since people have historically been labeled as queer and oppressed both on not having/liking het romances and on not having/liking het sex, both qualify them as queer.

(Note that it’s the lack of het activity that’s historically resulted in oppression, not the existence of same sex activity. This is also why arospec and acespec folks count.)
