Am I being overly sensetive.

am i missing something? Join the club!
then it's YOUR club.

I'd agree with this.
If it's a new bike club - it's probably a bunch of folks who knew each other and said "Hey! We should form a ride club!" - and you went and joined in and now they're puzzled by what to do with their own success (gulp! New folks actually joining the club!).
Ultimately, any group of riders will have folks of vastly different skill sets, and eventually, once it gets big enough, the group will, by necessity, splinter into different sub-groups.

Get the cue sheet - or have them make one for you - and offer to start up the "B" group rides. See if someone knows the area better than you who can initially lead a beginner group (or offer to lead it yourself). Encourage them to have their wives join you (if it's mostly guys and they're much faster than you - not making a sexist generalization here!). It's an opportunity.....Plus, as an added bonus, you'll meet more cyclists of your own ability and goals (b/c not everyone rides to go fast).
