So what all polyamorous are aromantic? I don't quite agree, alhough it fits my own experience. As a friend pointed out to me lately though, we probably (not we aro, we everyone) confuse romanticism with passion. I don't feel passion anymore (I'll get back to that) but I do feel what I can only call love for many people. I don't make a difference between friendship and love (at least there's not a qualitative difference) but rather different levels of comitment, frequency in interaction and so on. Some of those friends/loves/lovers I have sex with and then I don't, depending on what we both want at the time.
When I say I don't feel passion anymore, I think I used to (and no, I'm not entirely certain). I used to have the butterflies, to want to be the center of the others world, to spend time together and so on. As I see it, it all came from a deep insecurity which doesn't really bother me anymore. I discovered polyamory and things started making sense (why should I give the exclusivity of my capacity for attention and thoughtful relationship to just one person who is anyway incapable of giving me everything I need?) but I still felt passion, mostly during what is called "NRE". Then I healed most of my childhood issues and there's no passion anymore. I feel like Ive grown up and even though it looks like I lost something (something that looks like the ability to marvel and get engrossed in a person the way kids marvel at the world) it also really feels good. I'm more in control.
So, I'm not sure if I'm right but since noone seems to agree what romanticism (and as a consequence aromanticism) is, I would I fit the description. Which gets me to my point : to me aromanticism is the lack of passion, not the lack of love.
Feel free to disagree
