As others have said, without seeing the play we cannot explain to you why calls are made the way they are. The fact that you felt that the B/C calls were made incorrectly
even at the D-1 level makes me think that it is
you who is seeing things from a biased view (perfectly normal from players and/or parents to see things through the eyes of the team they are rooting for). D-1 officials are the cream of the crop and they get most of the B/C calls correct. But even they miss some from time to time because they are human.
At lower levels, (subvarsity) you may sometimes be getting very inexperienced officials. It takes a while to learn to "ref the defense" which is required in order to make the proper B/C call.
You should go ref a few games and make a few Block/Charge calls. Then ask the fans in the stands (from both teams) if they think you got them right. I'd bet you a week's pay that there would be fans who would tell you that you missed some and that they were "obvious as heck" and "how could you miss something so cut and dried as that?" Then you can give them your sermon and a B/C being objective and subjective.
