In no way was I meaning to imply that I was on board with what Dan Savage said in this video.
As Marcus points out, he's really not coming from the right angle.
My point was, however, that even outspoken advocates who you'd think would be defensive of poly are still critical. Even a progressive, socially liberal counselor could fall victim to that skepticism that Dan Savage espouses. It's an uphill battle to gain any sort of social acceptance.
Mostly, I think the public perception is that this is a trendy new 'thing'. I know a lot of young people (teenagers) that are keen to try it out and take it up, and of course they are making glorious fools of themselves. But at least they are trying.
