I agree that all the identity terms can be quite confusing at times, but I do believe it is important to recognise aromantic as a valid romantic orientation in its own right. (It is not the same as asexuality, but many asexual people are also aromantic). In short, aromantic people are those who do not experience romantic love/attraction, and therefore do not form romantic relationships. Of course, they do experience other types of love/attraction -- namely platonic, familial, queerplatonic, etc. Aromantic people are often abused and pathologised because others think they are "cold", "unsociable", "robot-like", etc. This is a misconception that arises from the false thinking that falling in love romantically is a necessary part of human nature, and those that don't experience romantic love are somehow not fully "human" or have some disability/mental health issue. Thus aromantic people often suffer a lot of bullying ("What's wrong with you") or exclusion from social circles based on falsely perceived "immaturity" ("You're not fully grown up yet if you aren't in a relationship/married by now") or in some countries, forced marriages or people constantly trying to set them up with potential partners against their will. It is important to respect aromantic people for who they are, and realise that they are just as capable of true, deep love and relationships as alloromantic (i.e. hetero-/homo-/bi- romantic) people, but their love is fully platonic and not romantic. Hope this clears things up a bit!
