Why do polyamorous people seem so intent on pushing it on others?

“You’ve been brainwashed to think monogamy is the only way”

Idk about you guys, but from what I noticed, I never met anyone who was physically attractive and poly. They all are either fat or ugly (even both).
To me, it seems like they have no choice but to be poly 💀 little options. They have to accept whatever they can get.
