No: anyone can choose which role to dance. Gender-free terminology is about making it clear that you can dance either roll regardless of your gender, but it doesn't mean anyone will have to dance a different role than they want.
Any time the caller would have said Ladies/Women, now they say Robins (or Ravens), while any time they previously would have said Gents/Men, now they say Larks. The difference is really quite small, but it's very important to a lot of people.
There are currently four contra dance series in Boston: LCFD, BIDA, Concord Thursday, and Concord Monday Fundraisers. And all four are gender-free!
This has been a long time coming. Boston's gender-free contras started with JP's LCFD in 1988. BIDA discussions started in 2013 and we switched in 2017. Monday fundraisers have been Larks/Robins since before covid, and the Thursday dance is going gender-free as they restart.
Since I don't know what regular Concord Monday is planning for when they restart this may be a temporary situation. But it's an exciting milestone regardless!
