Although it prevents wear and tear on one's hands, I feel I get less friction with the rock when I wear crack gloves than compared with bare skin. I rarely ever tape. So in my opinion, wearing crack gloves probably handicaps the climber's ability to climb. When I crack climb, a little less than half the time, I wear my gloves.
Hell yeah, real men and women jam skin to rock until their hands are a bloody mess. Training is also cheating. And being young and lightweight, super cheaty.
Enough people have chimed in to say gloves reduce their ability to jam that I have been switched from "crack gloves are cheating" to "NOT wearing crack gloves is cheating". End of discussion.
