“Yes, they are. However Frontier Airlines is subject to FAA rules on Exit Row passengers. They must agree to assist other passengers and the attendants in an emergency requiring egress through the emergency door on the row(s) where they are seated.”
The reason you won’t cite the regulations is that you know you are wrong.
(b) No certificate holder may seat a person in a seat affected by this section if the certificate holder determines that it is likely that the person would be unable to perform one or more of the applicable functions listed in paragraph (d) of this section because—
(1) The person lacks sufficient mobility, strength, or dexterity in both arms and hands, and both legs:
(i) To reach upward, sideways, and downward to the location of emergency exit and exit-slide operating mechanisms;
(ii) To grasp and push, pull, turn, or otherwise manipulate those mechanisms;
(iii) To push, shove, pull, or otherwise open emergency exits;
(iv) To lift out, hold, deposit on nearby seats, or maneuver over the seatbacks to the next row objects the size and weight of over-wing window exit doors;
(v) To remove obstructions similar in size and weight to over-wing exit doors;
(vi) To reach the emergency exit expeditiously;
(vii) To maintain balance while removing obstructions;
(viii) To exit expeditiously;
(ix) To stabilize an escape slide after deployment; or
(x) To assist others in getting off an escape slide;
Airlines are required to develop their own policies implementing these regulations. Flying regularly on Southwest, the standard instruction is always to "assist others", without specifying the exact nature of that assistance.
