Question: Charges vs. Blocks

[RangeGunner]

Basically, I was on the bench and approached him at half time. I did think he made the wrong call and then I usually research it. If I am wrong, I apologize and move on. I've played at the college level and I have never heard of this protecting yourself (other than covering your lower region). "In fact, the defender may turn, duck, step away" - I can duck and undercut him and he can be called for a charge????? This is completely foreign to me.

There is a lot of inconsistency in rect leagues. I got called for a carry because "after" my last dribble, I carried the ball over my head.
