Who's being sensitive?
Attendance was dropping for the enduros.
TSCEC is just adapting to the times.
TSCEC attendance was dropping because of the race experience, not because riders wanted sprint enduros.
Disorganization, lack of marketing and race information, mediocre course marking, antiquated scoring (until this year), and unreasonable wait times for sign up and results - that's what drove attendance down.
It will continue to decline as more sprints are added unless entry fees also come down. Less effort and less overhead should be reflected in the prices we pay.
"Just be happy you have races to attend" is also a wildly unhelpful mindset that allows for more of the above mistakes. Racers (like 2-smoker) should be able to voice an opinion without sarcastic remarks pushing any concerns aside. Especially when done as respectfully as he did.
Promoting a race series is a business, but TSCEC does not treat it as such.
