Y go for it. Sport is good teaches you many of life lessons and self defence you can use forever. Forgwt about kicking his butt though man is as a rule a more physically stronger but that doesnt give him the right to lay a hand on you unless you antagonizing him?
Why do your parents turn blind eye that sucks.
Yes. Get tough and learn how to defend urself. My brother is 6 ft 250+ and we've been fighting since we were kids. I've learned how to fight back at a young age. It's awesome taking down someone bigger then you. Trust me. He won't mess with u again.
so you get to kick him then claim it is just fun.
