Parents say trampolines are UNSAFE............shittttt

so i realllllly want a trampoline and me and my brother have enough to get like a 16 foot NICE trampoline. anyway i've been asking for one since the end of 5th grade (which was 5 grades ago) and my parents say NO!. they say they're unsafe, not because you can fall off, but because you can hurt your neck if you land on it right. supposedly you can be paralyzed or killed. but i know this will not happen to me because ive been bouncing on them forever. if this happened to anyone else and they finally convinced their parents please tell me what you said or if you have anything else 4 me to tell my parents. i want one so FUCKIN bad!
