Did I shit on poly people at all, or did I express a preference? I don’t want a poly relationship, I want a monogamous relationship, which I think I’m reasonable to want.

Non-monogamy is the logical extension of unlearning person-ownership

Like, that's definitely coffee-house sex philosophy truthiness. But it ignores the desire for someone(s) to come home to and rely on. A relationship is more than just getting off. And monogamy (or committed poly, if that's your vibe) is about building a friendship with the loved one and a community with their social circle.

You don't own your partner any more than you own your parents or your siblings or your closest friends. You just want to be near them regularly, because you love them. And when there's only so many hours in the day, you dedicate yourself to these people because you want a relationship that's deep rather than a series of flings that can only ever be shallow.

It's cool that you're non mono, I probably am too, but people are justified to prefer to be mono regardless of your personal opinions on relationship type

In no world will anyone convince me to share my person, to whom I don't own.
