I take issue with poly folks who try to make out that poly is some higher form of relationship, or that it is more evolved or whatever. I don't agree with that at all.
Those claiming that monogamy is outdated, outmoded and all the other things are not people I can get behind.
The issue I have with our society is in thinking that monogamy is the only way to be and the only way to have "good" relationships. I think I know as many people in bad monogamous relationships as I do who are in bad polyamorous relationships (and that is a ratio, not absolute).
I have a great deal of respect for those that choose monogamy and are making it work for them. I don't think we have any right to tell them they are wrong for that choice.
