I haven't found single poly people to be THAT rare. Perhaps its because I'm a bit younger but they don't seem to be as scarce as people paint them to be.
Where I ran into trouble was being a relatively single poly guy. Single poly women are highly sought after, single poly men...not so much.
I am as direct as a T-Rex with 'roid rage and about as subtle. It isn't intended to cause upset, I just prefer to talk plain. There are plenty of other people here who do the nice, polite thing much better than I can. I'm what you'd call a "problem dinner guest."
