@muggi: your issue is not that you think polyamory is superior to monogamy, it's that you have no conception of the fact that monogamy can and does work. You keep parroting the phrase "unkeepable promise" when it comes to exclusivity in a monogamous relationship; but you're ignoring the absolute fact that many people can and do keep the promises they've made to be exclusive in a monogamous relationship. You keep acting like your mindset is that of some superior, enlightened being who somehow knows that polyamory is the only way to acheive happiness, and that monogamy can never be successful - and then when the fact is pointed out to you that many people do acheive and mantain succesful exclusive monogamous relationships your only defence is to claim that despite all appearances to the contrary, you know, with your enlightened mind, that such people aren't actually happy. It's that which is so annoying about your polyamory crusade - you've taken it to the point where you're so convinced your theories are correct that you ignore fact completely.
