The word arrogance comes to mind
What a ridiculous question. Pilots fly aircraft. This is an aircraft and it will pay the bills. But if you are allegeric to turboprops or they are beneath you, then I you had better wait until someone begs you to fly a jet aircraft, one worthy of your status in the aviation community.
Truly, I hope this employer sees your ambivalence towards this job and gives it to someone who will appreciate the experience that this job will offer.
