I knew a kid in high school who became paralyzed below the neck because of a football related injury. I will not ,however, condemn football. I played it, enjoyed it, and continue to enjoy watching it.
If what the OP says is true, he has my sympathy, but I will not condemn Jelqing. I’ve had good results from it as have the majority of posters on this board it would seem.
Many everyday things, from lifting weights to driving a car, can be dangerous. One makes one’s own choices and faces the consequences thereof without casting ill will on others who have successfully survived those same said choices.
Such is life.
