I gotta side on the 'being overly sensitive' team.
I'm a member of a large club of very diverse women. Some rides are beginner rides, and some are not. I think you can't expect every ride to cater to everyone, and I would much rather know ahead of time that a ride is out of my league - for now! Some rides are no-drop, and others have occasional regroups, and some have none. As a club, whether new or small, they owe it to the other riders to have some rides that cater to them, and some that cater to you. Perhaps you can start your own slower-paced group that meets with everyone, but rolls out a minute behind at a slower pace. You get the commaraderie in the parking lot, and maybe arrange to meet for eats afterward - the fast group has to wait for a table and order drinks just as you roll in and sit immediately.
For 3 days, I get to part of a thousand other journeys.
