I agree with this statement.
However I don't really agree with the rest of your article per say, but whatever, you do you.
I am happily polyamorous, you're right it doesn't work for anyone, but I sure am happy.
However, I don't date men, only women.
There are a lot of annoying toxic straight men who seem to think that non-monogamy means they get to sleep with multiple women, but then freak out when their female partner sleeps with another male. Those guys are so annoying. There do exist good non-monogamous males, but the amount of straight dudes thinking all about their desires and not thinking about the long terms consequences, they are annoying, and they make a lot of noise. They're probably the ones you hear. Most of us Poly people are not about any of that.
