As a poly person, nonmonagamy must be consensual for all partners involved. Having sex with someone you know to be in a committed, monogamous relationship is immoral. At best, you are willfully facilitating someone else's victimization. We should not force nonmonagamy on others just as we wouldn't want monagamy forced on us. Obviously, the cheating partner is far more in the wrong, but you're wrong too.

Think of it this way, if you have a boundary in any relationship, romantic or otherwise, and someone else is aware of that boundary but helps break it, they're a shitty person for that. Just because we are wired for polyamory does not mean everyone is, and forcing it onto others and calling it "breaking their chains" is gross. This behavior could easily ruin lives and break apart families, and trying to take the moral high ground when forcing your beliefs onto others and victimizing them is frankly ridiculous. Nonmonagamy must be ethical and consensual, or we're just perpetuating stereotypes and harming the chance of future acceptance.

I hope you're just the manosphere troll you come across as, and not someone that genuinely believes these things. You hurt other poly people and monagamous people alike with these behaviors.

Yeah ok buddy, whatever narrative helps you feel better about getting your dick wet while you help someone hurt the person they supposedly care about.

If they need out help them get out instead of selfishly giving them an escape that doesn't actually help them escape and actually makes things worse. You aren't breaking the chains, you are helping her keep them on by letting her out to play in the fenced backyard before you crate her again.

Stop pretending to be noble and at least admit its selfish. Its not like its new, cheating has been around for as long as monogamy.

I am married, monogamous but would be into poly stuff if my partner was. But she isn't and im not going to force that on her. Its called consent, you should try it.
