This is a really interesting question! I've also certainly worried about this tension, especially in re: people's right to decline any dance. A friend of mine once described it in a nifty way: "you can always decline a dance" is consent 101. It's the basic lesson, and you really want folks (esp. the folks with societal conditioning against saying "no") to internalize it. After that is solid, though, you get to consent 201: "you can always say 'no', but there are all sorts of reasons you might say 'no', and it's worth thinking about where those feelings come from. Is it a matter of personal safety, or does this person not look like the people you usually socialize with, or...?"
I think my biggest follow-up question to you is: when you talk about wanting to empower people to say "yes", is this a need you've seen, or just think theoretically could exist? Even with the degree to which the dance community has started empowering people to say "no", the vast, vaaaast majority of people still do the twirls and still make eye contact, and I don't see people shrugging off those options just for the hell of it. So I guess I'm asking: what behavior are you seeing in these arenas that concerns you?
I will grant that declining dances is a thornier subject, because there ARE a bunch of folks in our community who people are less excited to dance with for some really unfair reasons (e.g. fat folks, disabled folks, etc.) This is definitely something we as a community need to talk about and address to make contra a welcoming space to all.
I know that my friend group tries very consciously to set examples of asking everyone to dance, and I've heard a good line (on SharedWeight?): "you never know who might give you your best dance of the evening." My personal check on myself (esp. at dance weekends, where I'm likely to be really excited about dancing with all my friends that I rarely see) is that I need to have at least one "mediocre" (quote unquote) dance per < day / session / etc. > -- which means I need to dance with someone who's less skilled, or with an unknown quantity/someone I might not otherwise dance with. (And then if they turn out to be a splendid dance partner, well, yay! I had better go ask someone else outside of my usual circle to dance.)
I also want to remind everyone that the burden of inclusivity lies not just on the ask-ees, but also -- maybe moreso? -- on the ask-ERs. Our concern should not JUST be "if we tell people (often women*) that when asked, they may say no, what if they say no to EVERYONE?" 1. Ask-ees (women) are not the gatekeepers of the contradance experience, but more importantly, 2. If we want to create an inclusive dance community, we also have to foster one where ask-ERs (often men, though decreasingly so) will ask everyone, regardless of age, size, gender, ability, etc.
* I imagine that the "empowerment to say no" disproportionately comes into play for women being asked to dance, so if we're worried about "being able to say 'no'" going "too far", that has some implicit gender behind it in my mind.
Final thought: we talk so much about how it's okay to say "no" because many of us -- especially women -- are so conditioned AGAINST saying "no". It would be a pretty cool problem to have, I think, if people felt comfortable enough advocating for their boundaries and physical limitations that we had to focus hard on empowering people to say "yes" again.
There are a bunch of (not necessarily organized) thoughts. Thanks for broaching this topic!
