I can kind of see what you're saying Lass but to me suggesting that 'no' is unkind, or refusing a request because you feel uncomfortable is unkind is a very dangerous place to go with girls
CallYourDadYoureInACult and I are talking about how dancing was taught in Scottish schools. Every year for a brief (blissful) period before Christmas we were spared PE and taught Scottish country dancing instead. This is in a school PE hall, in school hours with at least one PE teacher present (we usually had a mixed couple there) trying to get through as much as possible. The no refusing applied to both sexes.
If anyone felt strongly enough about it I suppose they could ask to opt out of the class entirely - but no one, boy or girl, got the option of saying you're too ugly or fat or uncool for me to dance with. You didn't get to pick the same person twice.
Many of these dances progress- meaning you move to a new partner after each set piece usually no more than 24 bars of music; or you are in sets of 8 where you progress through the set and dance with all the other opposite sex members of the set during the dance.
I disagree this is dangerous - I think it is more dangerous to set up the idea that girls are so delicate that, exceptional circumstances perhaps aside, they can't learn about something which features at almost every Scottish wedding and is an important part of Scottish culture.
